You stat matters little on inquisitor. Even if you have as high as 500 STR, how much is that comparing to the 8k base damage of inquisitor skills?
Also your stats would depend on what kind of builds you are trying to play. PvP or PvE as well.
For PvE I would suggest getting either strong damage builds such as cleric 2 diev 3 druid 2 inquisitor, or support build such as cleric 2 priest 3 krivis plague doctor inquisitor
For PvP you probably want something that ends with oracle - kabbalist - inquisitor. First 5 ranks are free picking (for example I’m going cleric 2 priest 3 oracle kabbalist inquisitor for supportive PvP build)
Stat wise high enough CON for about 25k HP (to survive 1 shot skill from archers). Then you can choose whether you want SPR for PvP, or DEX for PvE (crit is nice for big numbers of inquisitor skills), or even INT if you pick the diev 3 druid 2 path.
Like I said before, inquisitor is strong by himself, that’s why there are many ways to build an inquisitor, no need to get fixated on certain aspects.
