I would suggest finding an installer that still uses R-410A if possible, likely an overstock item with reduced cost. Supposedly, packaged 410A units are still being produced until 2028.

This is good advice.
I recently had our system inspected and had a lively conversation with the technician who has spent decades in HVAC. He was telling me about the AC lobby in DC that is involved with the constantly evolving types of refrigerants. Introducing a new refrigerant to a system involves lots of changes in components ($$$$) to keep it compatible and happy.
Planned obsolescence at it's finest.
