Some of my personal favorites:
Bahamut Lagoon (Super Famicom)
Dark Wizard (Sega CD)
As for homebrew... I did a quick search on pdroms.de, but all that jumped out was the Pandora port of Wesnoth... there might be something for one of the emulated consoles, hidden away without "strategy" in its description, so it may still be worth a deeper look.
