Dunno why you don't check what's done in Bookmark+.
It might present some food for thought, at least.

https://www.emacswiki.org/emacs/BookmarkPlus#HighlightingBookmarkLocations

Various kinds of highlighting are used.  Some of them
might be relevant for what you're trying to do.  Each
involves a style and possibly a face.

You've already started to consider fringe and buffer
position.

There are advantages to each kind of highlighting.
Those that use a face can (in principle) let users
tell the kind of bookmark from its face.  (That's
more important for Bookmark+, where you can have
different kinds of bookmark in the same buffer, for
different purposes.)

You might also check out the highlighting that bm.el
uses.

Just a suggestion.
