How well do you think RPG Maker works for specifcally Tactical RPG's, though? I'm sure it will probably feel less overwhelming for me than a full-fledged engine I've never used (even if it has similarities to laguages I know) and that it can very much still be done, but from what I know RPG Maker leans more toward Final Fantasy-styled game than TRPG's. I read that there are some plugins that would help, but I was still wondering if they really give enough freedom to make a grid-based game however the creator wants.
It's possible to modify RPG Maker to create the TRPG you want, but the problem is that modifying it requires a certain level of proficiency with the tool. If you use someone else's plugin (for example, I found one here: https://himeworks.itch.io/grid-battle-system), you'll be limited to what that plugin allows unless you know how to modify it.
If you search, you'll likely find templates for Unity and Godot. I found this one for Godot 4:

Exactly which path is easier depends on you and your prior knowledge. Personally, I would spend a few days with each option to see which one are more comfortable or which one as having more potential.
