Best option/device to portably emulate SNES ROMs on my smart TV?

For a while now I've wanted to pick up a hacked SNES or Raspberry Pi in a small SNES case to emulate my favorite games on my TV. It's both for me, and for my daughter (5) who has successfully played games like Spyro Reignited with little help from me. I think SNES would be an incredible entry point for her. That said, after some digging it looks like a Gen2 Amazon Firestick may be the better option?

Just hoping to get some advice on the simplest, most straight-forward option for me to play SNES ROMs on my smart TV, with support for two controllers. I'm even open to buying a complete package with the work already done for me, so long as I can add ROMs of my choice to it. I just don't know where to get something like that, and everything I've searched looks a little overwhelming to put together. I'm fairly tech-savvy, but I don't know that I'm up to the task of physically assembling devices and circuit boards like some of these kits seem to require.

Your advice is greatly appreciated!
