We named our daughter Matea, and at least when we were in the USA, her name was rarely mispronounced (which is pretty good for the land of the world’s greatest mispronouncers!). Avoid names with ‘j’ (few cultures unexposed to Slavic and Germanic languages understand it’s pronounced like ‘y’), ‘i’ (at least in America, default pronunciation is like ‘ai or aye’ - which is why we didn’t spell my daughter’s name like her Grandmother Matija). And of course any of the special letters š đ č ć ž and combinations like nj, dj, and lj will be a problem (but thats covered already under ‘j’). I think you have some pretty good name suggestions already in the responses.
