I also use KeePassXC, having migrated from Lastpass in 2015 after they had a security breach and I decided it perhaps wasn't the best idea to have a database of all my passwords online. I'm pretty happy with it. The only more advanced feature I use is the built-in timed-OTP store, which is pretty handy for a few websites that insist on two factor authentication but, in my opinion, don't really warrant it (the browser extension can fill in username, password and one-time-password in one fell swoop, saving having to mess around with my phone). I believe other password managers are starting to have this feature now too though. I use Keeper at work (which my employer pays for) which also has TOTP support.
