I should get into Fire Emblem again someday, I only played the first game in the series lol. When I get a Switch 2 I would like to get Fortune's Weave for sure. I own Radiant Dawn on the Wii, one of my friends gave it to me for free in the past.
If you get Fortune's Weave then I suggest get 3 Houses too, because by completing 3 Houses you'll get a lot more kick to Fortune's Weave Story, very tightly linked storywise. Though of course you can play Fortune's Weave only without 3 houses, the game gives you a clear enough story too as a stand alone thing,
