Unless you use a small local bank - I see no reason to switch your current banking plan.
We were Chase customers for many years before going full-time and have found it useful.
As an example - while we were recently in the Rio Grande Valley of south Texas for work on my dentures in Mexico, we picked up a medicine for a friend in our Good Sam chapter (yes, we showed it to customs as we came back across the border - she assured us it would not be prohibited, and it wasn't.).
A couple weeks later we met up with them and gave her the medicine. While at the table to eat lunch, she gave me a check for the costs. I used the Chase app to take a picture of the check and deposited it in my checking account. Gave her back her check for her records. It was done in a minute.
Other banks have similar apps.
The only time we have to find a Chase branch is if we need a large amount of cash or to deposit a large check.
The 'go to' place for cash for us most of the time is Walmart. Buy something and get $100 or so cash back. Most large supermarket chains have the same policy.
We almost never us an ATM. Chase does charge us a fee if we get money at someone else's ATM. So we avoid those.
We know people who use credit unions - I have an account with Navy Federal - since 1972 - and I'm amazed at the number of places I now see Navy Federal Credit Union branches.
Get to know / use the smart phone app for your bank. You will likely find that you can do everything you need / want without ever going to a bank.

Walmart - you might not be a Walmart shopper. You will be as a full-timer.
I love the regional stores we run across - if you are ever near Hartford CT - be sure to go to Stew Leonard's Supermarket. A wonderful experience.
However, there will be many times when you know what you want. You want to go into a store where you know where to find it, know it will be there, and get out.
Walmart fills that need. They have a few basic designs, carry almost exactly the same brands in the same location in the store. Everything from food to socks.
While in south Texas HEB supermarkets carry 70-100 feet of shelf space of Mexican/Hispanic food items. While in Connecticut - Stop & Shop supermarkets carried 30-40 different brands of pasta/ spaghetti sauce and 15-20 different brands of frankfurters at the fresh meat or deli counter.
Walmart carries the same stuff anywhere. Sometimes that is a good thing.
We used Sam's Club when we lived in a house - because we had space to store bulk purchases. We don't have that space now. We have a Costco card because it saved us a lot of money on hearing aids for the wife. But we don't buy very much there. Did replace the trailer batteries this year at Costco. Might buy truck tires there next year.
