Would I be able to access my Windows files if I am to make a dual boot into Linux?
Yes.
Most desktop environments allow to transparently open NTFS drives just by browsing "My computer" or whatever there is. There's been no need to mount
(a Linux console utility) Windows partitions for many years now.
The biggest issue of using Linux along with Windows has been and remains to this day is dual booting. It might get complicated depending on your hardware and partitioning scheme.
Whatever you decide to do, make a full backup of your data and verify you've actually backed up everything. In Linux it's a lot easier to destroy all your data than in Windows.
Installing Linux on a separate disk might be a good idea.
Lastly, please consider using Fedora Live image (Fedora 36: x86_64 Live ISO) for a while to get a feel of it. Linux is so drastically different in many aspects you may decide it's not worth it.
