I wouldn't worry too much about stats progress now since there's a level down/up trick you can use to max any stat except avoid percentages. Basically use a mind flare(squid like monsters) lvl
down skill on a bard/dancer to minimize the stat decrease for each level then level them back
up with a class with better stat gains. Note mind flare's level blast skill is only available when he is right next to a human with "monster skill" ability from the squire class.
This is a rough chart on which class has best gains, personally I level my physical char as half ninja half monk, and my mage char after acquiring all math skills they stay as wizards.

BTW math skills basically > the entire game it's not even that difficult to beat entire game with just the main char..If you like the minor challenge give it a try I've done it few times with end game set-up like this
Ramza or whatever you named him 97 brave 70-97 faith
squire class:
2nd skill-math skill ofc
reaction-dmg to mp
support-mgk attk up
movement-move mp up
equip:
weapon-excalibur
shield-aegis shield
helm-thief hat or flash hat
robe-wizard robe or robe of lords
glove-genji gauntlet or magic gauntlet
You should move first with haste from the sword, and since it absorbs holy feel free to holy yourself to heal as well as to kill most enemies. Math skills ct/5/4/3/prime at the start usually can hit most if not all enemies. If you get targeted by attack mp switch will save you from losing hp no matter how much dmg it is with a 97% chance, and walking around restores mp. >:D Look up gamefaqs for more detailed version I feel like I'm writting a while guide here
