Keep the boot sectors for Linux and Windows separate. Windows loves to fubar the Linux boot instructions during update. They somehow still manage to break the Linux boot section even when it's on its own isolated sector, but it happens a lot less frequently.
AFAIK you can't use drive encryption when dual-booting on the same HDD.
Unless you have a reason to keep Windows, for example some software you depend on that doesn't run under Linux, just get rid of windows. There's no real reason to keep it around if you don't need it for a particular reason.
If you use two drives, I'd highly recommend getting two different models of SSD because after around kernel version 5.18, the kernel will reject one of the "duplicates". Was a huge source of frustration when I started, and I had to use Mint for a while before finding out the problem (I'm on Arch now btw)

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
