My only Olympus bodies are the air-01 (weird 16mp sensor that pairs with a smartphone and has minimal controls and lacks ibis) and an EM1. I’m not sure the size of the em-10. I would use camerasize.com or a similar tool to visualize the selected body and lens combo.
My stable of m43 gear in size order smallest to largest:
Olympus Air01 - no viewfinder, hard to control, no ibis. I sometimes take as a backup when space is at a premium. (Don’t buy, no viewfinder, no ibis, too weird)
Panasonic GX1 - external viewfinder is pricey and adds bulk but is a nice option in your bag or pocket, no ibis, weaker image quality than other 16mp bodies I’ve used. Lcd screen commonly has coatings mottle and look terrible without power on but this seems to have little impact on image preview oddly. (Too expensive with viewfinder added on, no ibis)
Panasonic GX-7: great feel and size. Integrated TILTING viewfinder which is fantastic when bending over, ibis (3 stops perhaps), strong iq performance, titling screen (I prefer over articulated screens), one of my favorite cameras of all time. (Under $300, DFD focus only works with Panasonic lenses, CDAF performance with my Olympus 60mm macro is plenty fast for me, great fun camera)
These next two are nearly the same size.
Olympus EM1: Nice EVF but non-tilting, tilting screen, great IBIS, PDAF focus support, funky control layout - I hate left side power button and I struggle with the dual mode controls wheee flipping a lever gives different functions, no touchscreen if that’s important to you (not really much of a factor to me), grip capable - I have it and don’t tend to use it, weather resistant. (Prices seem to vary more than others. Some are within your price range or a bit higher, flagship class body is NICE)
Panasonic GX8 - tilting EVF, simple (for me) menus, articulated screen (sigh), larger body, improved IBIS, not quite as good as EM1 probably, good controls, good feeling in hand (em1 is similar or better), 20mp sensor, AA filter - all of the others are similar in this respect, lighter feeling than size would suggest but solid, same focus type as GX-7, weather resistant. ($500’ish, too much for the budget)

Camera bodies for size comparison. The air-01 is shown in one shot paired with a Motorola Z4.
