When I got my new Dell laptop I knew setting the display configurations would be problematic.
In the W10 forums there are sets of reg files for 'Menus', 'Title Bars' and so on that allow you to set custom font sizes for all these. Microsoft used to have these as a user option back in W8.1 and earlier but dropped it some years back. You can also choose Bold if desired.
I made notes for future reference which obviously apply to my preferences, but this gives you an idea.

All the other files are easily found on W10 site. After applying each file you need to sign out and back in to apply it.
