A monorepo is certainly worth the consideration, but there are other options if you leverage CI (such as dependent builds).

I was functioning as an architect at a pretty large company and we used spring boot. My team wrote a number of internal starters (and our own parent Pom) that all other teams would use and set it up so that the services would build/test/deploy after our base pom and starters would release. It obviously takes a bit of time and tooling to do that, but it was working quite well for us and still kept us from needing to update the same thing manually in 20 places (that is until we’d need to release a breaking version).
