Going to be doing a bit of a refresh on this old mixte, currently single speed/coaster brake. It would be nice to have a couple gears, but it seems that the 110mm real hub spacing is going to make that a little challenging.
I’m certainly not expecting a ton of range and I’m open to a derailleur or IGH, but I don’t any to spend a ton of money on it either way. Are there any reasonable option here or do I just accept it?

Not feasible
Are you sure you can’t stretch the frame to 120mm? Looks steel. Shimano nexus 3-speed is 120mm. Maybe a freewheel with 5 gears will fit in 120mm with a claw derailleur and a friction (downtube?) shifter too, if you can cut the freewheel spacer on hub axle, but I’m not sure about that last one.
Triple in front, single in back. Something to take up the chain slack.
‘Cold setting’ is pretty easy to diy to spread it to modern sizes.
Sturmey archer makes a 2 speed kick shift in 110mm hub spacing, with or without coaster brake. You probably won’t find a pre built wheel like that though
New bike
Maybe a hub meant for a Brompton? They are 115mm.
Sturmey Archer and other 3-5 speed variations are available in 110mm. You can increase the range by running a doublw or triple up front, too.
