Yes, it can run all that. You may have to jump through a few hoops (just like in the case of the Steam Deck, just different hoops), but it can run all that.

I'll also turn your question back to you: how many people use the Steam Deck for productivity, rather than for gaming, which is its intended purpose? And does it matter?

Like it or not, the steam deck is a gaming console, even if you can run non-game stuff on it too. Heck, even stuff like the Game Boy had (official!) accessories like the Game Boy Camera and Game Boy Printer, which were both useful outside of gaming. Does that stop the Game Boy from being a (retro) gaming console? There's an ongoing project to provide productivity apps for the Game Boy (though, arguably, it did not ship yet, but you can extend the game boy with a cartridge in whatever way you can imagine).

Or, you can use your SNES as a MIDI Synthesizer (https://www.supermidipak.com/)! No modding or anything necessary, it's just a regular cartridge. Can it be used for fun? Yes. Is it a game? No. You can do a lot of stuff with an SNES cartridge that has nothing to do with gaming. There was even a cartridge that let you play online games on the SNES (https://en.wikipedia.org/wiki/XBAND) - but not only games, it also let you read and write messages to other people. You didn't need to go into "desktop mode", nor install a browser, nor do anything special. You plugged in the cartridge, and it worked. It was far less locked down than the XBox or even the Steam Deck! Does that disqualify the SNES (or the game boy) from being a gaming console?
