I've tried DBLibs a few times and never liked them. A few years ago on a team of 3, we settled on just keeping IntLibs under Git control and telling each other if we made any edits to avoid merge conflicts.
These days, especially if the entire team is on up to date Altium subscriptions, I'd say just use A365. A365 is, among other things "team library management you just don't have to worry about anymore." Concord Pro is a set of features ON TOP OF that around lifecycle and release management that you can decide whether or not you care about (but you personally don't, so don't worry about it).
I know the Altium subscription I just (finally) bought myself includes A365 for free, and it sounds like that's probably not a special, limited-time thing: I think the whole point of A365 is to give people who don't really care about updates or support a set of reasons they might want to maintain a yearly subscription.
If your team's subscriptions don't come with A365 automatically right now (which I think they should and probably do), I'm betting you can just call up your sales rep and say "hey we don't seem to have the 365 features that we're supposed to" and make them turn it on.
Seriously, A365 AFAIK has literally two main features: turnkey data management, and third-party data access with granular permissions, for use-cases like "show the vendor this whole design without emailing .zips." It's not earth-shattering, or crazy, or anything. It's just a way to solve this specific problem you seem to have right now, and keep you paying the yearly subscription fee you already are.
If you're rigorous and nerdy with data management and git and libraries and all the rest of it, you probably don't need A365. If, as it sounds is your case, you just don't want to DEAL with that, and just want a system that works well without effort, A365 is probably exactly what you want.
Best part: if you decide it's not enough to justify paying yearly, you can seamlessly export all your data, and relatively easily. Projects are JUST git repos hosted on 365 instead of github, and with a good altium-specific viewer in the web interface. Libraries are vaults, but can be exported to schlib/pcblib/intlib as you please (and are versioned as well).
