I would advocate for using each tool, where it makes sense, to achieve a more intelligible graph. This is what I've been moving towards on my personal projects (am solo). I imagine with any moderately complex group project it becomes very difficult to keep things neat.

In order of expected usage frequency:

1. Rebase: everything that's not 2 or 3. keep main and feature lines clean.
2. Merge: ideally, merge should only be used to bring feature branches into main at stable sequence points.
3. Squash: only use squash to remove history that truly is useless. (creating a bug on a feature branch and then solving it two commits later prior to merge).

History should be viewable from log --all --decorate --oneline --graph; not buried in squash commits.
