The typical English name for that is Canaan. There’s a lot of history surrounding that name in the Bible (OT, so shared by Jews, Christians, and somewhat accepted by Muslims too) and a lot of it not positive.

Personally I don’t really see that Palestine is a bad name as it’s really just a name for the region and the only baggage it has is quite modern; Zionist Jews might prefer some acknowledgement of the land as Israel and so it would be tough to get them to accept something that doesn’t include that IMO
