First, I would like to extend my most sincere thanks to @UncleB and @Birdman7 for all of their sage advice and support over the last few weeks as I prepared for this. I also want to show my appreciation to the entire myFICO forum for all of the DP's and posts which I used as a guide to make my decisions. This community is outstanding and invaluable, and I am posting all of my DP's in return so that they might help someone else.
My credit DP's at the start of the day:
FICO: 765 across all 3 Current: SmartOption Visa (0/$2,500) - Local Bank, Low APR
AAoA: 3y2m Citi DC (0/$5,500) - 2% everything
UT%: 18% Discover It ($3,000/9,000) - 5% Rotate
INQ: EQ/2 TU/0 EX/0 Truck Loan - July 2018
Income: 52k
Last CC App: Sept. 2015
Location: SC
1 - Barclay Uber Visa - Instant Approval $8,000 - (9:45am EST)
Pulled TU - (as they usually do)
2 - US Bank Cash+ - Instant Approval $1,000 - (10:15am EST)
Pulled TU - (Did not seem to conflict with the Uber Visa app, thankfully)
From my understanding this is considered an instant approval, not a manual review. I do plan to Recon the SL for this one, however, I don't know if I can do this now or if I have to wait for the card?
Edit: Recon SL adjusted to $7,000
3 - BoA Cash Rewards - Instant Approval $6,000 - (11:00am EST)
Pulled EX - (I had a preselect mailer with an invitation code for this one)
4 - FNBO Ducks Unlimited - Instant Approval [Ammt TBD] - (9:30pm EST)
Pulled EX - (I took a chance on this one, but the prior BoA pull didn't seem to affect it)
I did notice on the splash page as I submiited my app, there was a picture of the DU platinum Visa. However, the approval I received states Signature Visa which I think indicates a $5,000+ SL ??
Edit: After checking the online approval site, SL received is $6,000
I think I covered most everything I can think of. If anyone has any questions I'd be happy to offer any other feedback I can. And if anyone knows about the US Bank Recon SLI (whether I can Recon now, or if I have to wait for the card) could you please let me know? I will edit later to reveal the results of the Recon.
This has been quite a satisfying day and if you'll excuse me, I will be at the Home Depot purchasing fertilizer and some shiny new spades and hoes for my 2-yr hiatus. Cheers! 
UPDATE: As of today (3/26/2019) My Recon with the US Bank Cash+ SLI was successful! The SL for the card has been adjusted to $7,000. In addition, I also received in the mail today my Barclay Uber Visa and my BoA Cash Rewards cards. Finally, regarding Ducks Unlimited, I checked the online approval site for my SL and it states $6,000.
So, prior to 3/11/2019 my overall revolving CL was $14,500. I received $2,500 total CLI's between my Discover and Citi DC taking me to $17,000. And now with these new additions my overall revolving CL is $44,000, tripling over the course of 15 days.
On Deck: No Plans Currently
Absolutely fantastic!
Congrats on the strong approvals, and come on over to the Garden... you'll be in good company!
@UncleB
Move over.....(hands you a Jack-n-Coke)....I need to be facing the beach.
The really ironic thing: I've been sitting here looking at my wallet thinking.....my first purchase may very well have to be a new wallet. Lol!
@Saeren and @credit_is_crack
Well if that's the case, then I'll have to tactfully Recon them, as well. I understand the argument regarding "credit seeking behavior" but every one of the cards I applied for has a specific purpose for me. It was a calculated process to get cards that give a return on my monthly expenses, and although some may see it as excessive, it was by no means abusive behavior. I can only hope for the best.
Citi Dc - 2% everything
Discover - 5% Rotate
US Bank - 5% Utilities and Cell Phones
Ducks Unlimited - 5% Gas , Sporting Goods
Uber Visa - 4% Restaurant/Fast Food 3% Travel/Hotel/Airfare
BoA - 3% Online Retail Shopping (also needed for a BT from my Discover)
@Overmedicated
I have read through most of those posts during my research and it is discouraging, but worst-case senario, if they do retract the credit line then I can simply re-apply in 2 years if I choose. Or I can simply apply for the Cap1 SavorOne or the next flavor of the month credit card that comes out with restaurant spend. They will come. Barclay would only be hurting themselves as my dining expenses are the highest spend I have just above utilities.
And I will argue that I haven't opened a CC since Sept. 2015 (3.5 years) so I'm obviously not a churner or an abusive card user, as I also PIF each month. (The only exception being the Discover which was unexpected expenses while we are currently saving for a house, so a BT allows me to stretch that debt a little.)
And honestly, I see no difference in myself applying for all the cards that are useful to me at one time to age my accounts together, than someone who applies for a new card every 6 months like clockwork and holds 31 total CC's (and in most cases I would argue that those are the people who don't really need that much credit and are actually abusing the system) I live within my means.
But for now I am relatively happy with my results and will cross whatever bridge I come to. And I will be getting CB on the way to that bridge...
