Wanderign trader improvements

general concept is fine, getting things across world, but what he gives seems more like items for players on giant old worlds to get access to some things from new biomes added later
wandering trader is honest and hard working guy so he should offer more in my opinion

turtle eggs could be one of things sold, or buying them back, maybe some unique llama carpets, those are smaller and less interesting ideas

music discs, he could trade common (drop from creepers or located in general dungeons) music discs, maybe for trading for other of general music discs, he maybe is collector

sherds, unique about this would be that he would serve only as way to duplicate those, so you would still have to have at least one already, issue is that to have bunch of matching pots, you got to get trough many archeology locations and they arent renewable, given how many kinds of sherds there are, it should be just universal, it isnt OP in my opinion, as he would not show with sherd dumplication offer every time and his stock seems to be very small and as told, you have to already have item in first place, so doing archeology cant be just skipped for this and may be easier for initial stock of sherds

trader station, would work similarly to work station for villagers, but also as lightning rod, if trader is to spawn at some radius, spawns on/next to station instead and hangs out near it then, helps with both, finding him and prevent from annoying at areas you dont want to be bothered by him, when he spawns
