Apple has been keeping the user experience a priority in all their latest updates, and Linux desktops are more usable than they've ever been. There's absolutely no reason to use Windows 7 for anything important if Windows 11 is a dealbreaker.
Microsoft isn't about to reverse course and make Windows good again, so if you've already decided not to use Windows 11, start the process of acclimating to a new OS now, rather than stagnating on a dead OS that is only going to get less safe to use moving forward.
If budget is a concern, I promise you your Windows 7 PC will run Linux. If you are experiencing the sunken cost of all the Windows-exclusive software that you have already purchased, then pony up for a Windows 11 PC, because you're not going to survive on a EOL Windows OS for very long.
