Not sure anything existing will do all of that, but in terms of FLOSS
with a self-service web UI I think this mostly boils down to Jagger[1]
or PEER[2]. There certainly will have been other wheel-reinventers but
I'm not aware of them having shared/opened up their tools.
(Most federations[3] probably have written their own thing at some point.)

Jagger decomposes metadata into individual data elements, storing the
pieces in a custom schema in an RDBMS (reassembling them for output)
and has custom web forms and business logic for all editing
jobs. GEANT has spent some effort a few years back trying to make the
UI more consistent.
PEER takes a more document-oriented approach and uses git as backend,
but the included JavaScript metadata editor[4] is a bit weird, has a
few mis-features and could generally use some love (or replacing[5]).
I'm not aware of either tool having published APIs.

Other than that: I recall the UKfederation announcing in 2016 to
invest in creating their own tool (obligatory xkcd reference
https://xkcd.com/927/) that will have APIs plus a web UI.
Here's an archived presentation[6] of that (relevant part starts at
42:10) as well as the slides used[7].
