I also like rebasing. Sometimes my squashing cannot be completed without manual intervention, so I'll do a squash merge into a temporary branch instead:

   git checkout main
   git checkout -b squash-branch 
   git merge --squash [branch-to-rebase]

At this point I usually git diff the two branches as a sanity check before merging back into main:

    git diff [branch-to-rebase]
    git checkout main
    git merge squash-branch

I am normally able to squash rebase 99% of the time using git rebase -i main, but doing a git merge --squash into a temp branch has saved me a lot of hassle over the years.
