I think it depends on how high end of a Unit you’re looking to get

Look into a quality water softener, Express Water has a good quality lower cost unit

As for a Combi, Burnham Alta or a Laars Combi too not break the bank. Just units I prefer some, lean towards a Navien.

current unit is takagi model AT-KJR3U-IN

continuous lockouts

Keep the Takagi for domestic hot water and get a decent, small mod-con boiler for radiant heat. Flush the Takagi unit of hardness. Don't get Navien.

he had said room is limited so seems like he needs a combo unit

got room for a tank? A combicor would be a simple reliable option. Plenty of DHW and a nice buffer for that tiny heat load
