Camera recommendations, looking to upgrade from a fuji X-E3

Hi,

I'm looking to upgrade from my fuji X-e3. The camera itself is ok, but I'm getting tired of some things about it. I prefer to buy used since my budget is limited.

What I'm looking for :

-small form factor, i'm travelling with it. The x-e3 was perfect on that aspect.

-WR ! One of the biggest flaw of the x-e3, I want to shoot in light rain without worrying too much.

-Colors, SOOC from x-e3 are nice, but the color in raw always looked weird to me.

-APS-C sensor or larger. (I shoot at night, I do alot of long exposure and use mainly a UWA lens).

-Ibis would be great.

-16mp or more.

As of now, the lens I use the most is a 13mm from viltrox. I also have a ricoh GRII that I love.

thank you !!
