I wasn't playing guitar for nearly as long as you, but I was an "established" guitarist.
I was third guitar/lead vocals in a band and we lost our bass player. I've always been a team player. So ...
Your first point, "avoiding playing like a guitarist": I believe coming from the guitar helped to make me a better bassist. Unlike so many "frustrated guitar players" who switch to bass, I was never (and I never say: "Never") a ride-the-root-tone type.
We played hard rock/metal and I riffed (appropriately); like a good bassist should do in certain songs/styles.
I was self-taught, translating what I knew about guitar playing to playing the bass. I worked with the drummer to find interesting ways to transition between phrases or progressions.
I worked hard to lock in with the drummer; even more so than I did as a guitarist because I'd come to understand the bass truly is the pathway between melody and rhythm and back, again.
Since I am no longer able to gig (and live in an area where there isn't much demand for studio bassists), most of my "projects" are either recording by myself or remotely with others.
When recording by myself, I'm it. I play both (and love it). When playing with others, it depends upon what's called for. There are lots of guitarists who are convinced they can just pick up a bass and be a bassist. As we all know, with that kind of attitude, they're usually mistaken.
Because of this prevailing (seemingly) view, many guitar players don't want to bother with bassists (heck, lots of them don't even like working with other guitar players [but ego is never an issue. No ...]).
Primarily, I work with a drummer and will occasionally invite a guitar player to be featured.
My biggest piece of advice: Don't turn your back on your guitar playing past. I firmly believe it will make you a better bass player (and don't get my started on keys, relative minors, sevenths, etc.).
Good luck and if I can help ...
