AFAIK any quality VFD made in the last 5+ yrs will be sensorless vector drive, at basically the same cost as earlier VFDs.
Hitachi WJ200 is a sensorless vector drive. It's not super-expensive, and it's a Hitachi. Yes it has a Modbus driver for it. HY has worked ok for people, but I would never consider it, a reliable WJ200 is only a bit more $.
