Why are you interested in Kabbalist ? For the HP buff ?
With the build you linked, you’ll be mainly a Healer/support, although anyway a Paladin cannot be a “real” tank.
If you don’t care about PvP and will focus on PvE I’d say you’ll need more than 100 SPR for your buffs and heals, since you’ll most likely be the healer of the party.
But you can go almost full CON, while dropping a few points in SPR here and there.
You don’t really have a need for INT if you don’t choose an INT-based attack class.
Although if you go Cleric 2 then Priest 3 it’ll be annoying for you to level up, that’s why some people invest in STR or INT, or/and also choose a class that will add extra attack skills.
