You can give
Vandal Hearts 1 another go, SAT version (superior to PS1 one) is now translated:

VH2 is also decent, completed it in June using the "Take Turns" hack, which fixes its bizarre original combat system:

But! My
holy trio chad quad after playing ~95% games mentioned ITT is:
1) Tactics Ogre - LUCT (
SAT version is the definite one)
2) FFT (+ My Mod, which reduces grind for JP a lot)
3) Front Mission 3 (one of the most complex content-wise japtacticals - two scenarios, mini-internet, etc.)
4)
Der Langrisser (Snes, remake of L2 for Genesis) and
Langrisser I: The Art of the Swords War (Windows 9x, remake of L1 for Genesis) for reasons mentioned above:
Modern PC remakes of Langrisser 1&2 are nice, but much easier than Snes / PC remakes, which are easier than Genesis originals (but still quite hard).
Everyting else is IMO inferior to these 4 games, and Fire Emblem is ITZ own thing / different subgenre (permdeath, criticals, guides required for getting and using good units), etc. Give either
FE4 for Snes,
FE6 for GBA or FE9 for Gamecube a try, and if you like them, you can go back to Snes games and forward to NDS / 3DS games. Modern Fire Emblem games (Switch) are IMO cancer, mostly for gameplay-related reasons, but writing and characters are even worse.
