I got mine in December. As Credit Curiosity mentioned, they are invite only for unsecured (you can't go to their s website and just apply.) So, unless something drastically changed in your report, it's about as close to a sure thing as you can get with CC approvals.
Based on your scores and recent cards, I don't think you need this one. While it will serve a purpose for me right now, you've already hit the milestones. There are no rewards, and by all accounts I've read, they are slow to grow because CLIs, while somewhat frequent, are small (however, I can't fully confirm this, as I'm still in my first few months, and my line had not doubled.) I might be wrong, but I believe their cards cap out at around 3k or 5k. It won't ever have the distinction of being your highest limit card (well, maybe, but it will be quickly overtaken by another card, I'm sure.)
I suppose you could get it for utilization purposes, if you're nervous about apping elsewhere due to your inquires, but honestly, I think you could get yourself a card that will give you more benefit if you're really itchy to app.
Another thing to consider: they are somewhat slow to post transactions (purchases and payments.) It's not unusual for it to take 3 or 4 days, and I know it's not the merchants being slow to process batches. And their website, while serviceable, is a little archaic. No whistles and bells there.
One good thing is you get your FICO8 score, though I can't figure out which one. I get the 3 score monitoring here, and the Merrick FICO doesn't match any iteration of the ones here since I've subscribed.
