I’ve upped my tank size again. Would any of these fish be a good fit?

You could do 2 same species dwarf angels in one tank if they're a pair. I'm not sure about other dwarf angels, but all coral beautys are born female and the dominant one becomes a male. So, you'd have to get the smallest coral beauty you can find and the largest one you can find and they'll become a pair.

Your tank is nearly the same size as the tank I just ordered. I’m setting up a 36” x 26” wide x 28” tall (115 gallon) peninsula to go right next to the arm of my couch. However, on the opposite side of the wall is a bedroom closet and I have plenty of room for sumps and quarantine tanks and whatnot. I’m not afraid of fixing sheetrock when I put holes in my walls.

If you’re looking for a larger fish, why not add a bunch of smaller fish, like flame anthias or blue/green chromis to make a 5” or 6” appear to be larger? That’s part of my plan with my tank. I want the majority of my fish to be flame anthias and when I get a 6” chaetodon tinkeri, it’ll look larger and contrast sharply in colors next to the other fish.

On LiveAquaria it says the minimum tank size for the 6” butterflies is 120-125 gallons but I only have a 100. Would that be good enough?

Getting a quarantine tank will also be a challenge. Here’s a video of my apartment and some pictures.

It’s a second floor apartment, unfortunately, and only 23sqm (4.79mx4.79m).

Marine betas too big and an expert fish one spot would be fine as long as you have algae for it to eat

Have to completely disagree here.

Very easy to keep and your tank size is fine.
Mine just hangs out, not an active swimmer, doesn’t bother other fish or inverts including shrimp, eats all foods. A perfect citizen that’s easy to care for.

Slow growers, you wouldn’t have any problems. I’ve had more than one throughout the years.

Rabbitfish do get big.
Klein’s are good with eating Aiptasia. Personally don’t think they’re much of a looker but they’re easy to keep and don’t require a big tank. But always have to keep an eye on them with coral.

Would a Marine Betta eat my smaller fish clownfish, YWGs, Basslets, Wrasses, or even a dwarf angel?

As for butterflies, LA suggests a tank size of at least 120 gal for pretty much all of them including Klein’s. Would a 3-foot tank that’s 100 gal really be okay?

If I can’t get a butterfly or a Marine Betta, my next alternative that I’m considering is putting two dwarf angels. Could be a pair of African Flameback / Atlantic Pygmy, or I also wonder whether it would be safe to mix species. From what I’ve read 2 Coral Beauties or Coral Beauty + Flames are not a good idea. I’m thinking more along the lines of Coral Beauty + Atlantic Pygmy / African Flameback, Coral Beauty / African Flameback / Atlantic Pygmy + Half Black / Rusty.

You’re fine with getting a Marine Betta.

Two dwarf angels may be a challenge.
