The good thing here is that you are also showing Wells Fargo that you have a need for a higher limit and can manage it responsibly. TBH, with a 739 score, they should have given you a CLI already. I'd say give this card another year and see if it grows. If not, then put it in the sock drawer and charge $5 to it every 6 months.
I think people often get stuck in a cycle of cards with lower limits when none of their current cards will go up and they can't neccessarily get approved for new cards with higher limits. If you use Target, it will definitely increase over time.
You might also look into getting a Capital One card. With your scores, you likely would not have any issues getting approved, even with baddies, and many people report getting decent starting lines with them. For you, I would recommend trying the prequalification tool and selecting average credit. The cards for average credit tend to have higher starting lines and grow better than the starter cards. Their no annual fee Quicksilver card would give you all the same benefits as your Wells Fargo card. They also have the Savor One card for average credit that does a good amount of cash back on dining (I believe it's 3%, with some 2% categories, and 1% for evrything else).
