A simple fix for race builder is to use the static feat trait to add either extra SP or Basic Magical training with a specific sphere. Probably switch it so that these traits count as magic traits.
E.G. Treelings are naturally magical and good with plants
(2 RP) Extra Spell Points
(2 RP) Basic Magical Training: Plant Geomancy
I like this option because non magic characters gains 3 SP and the basic sphere which is enough to do things about 3/day which is how many native spell like abilities work. They can also take advanced magical training to buff up their racial spell casting ability without taking any casting classes which is cool.
Casters instead gain +2 SP and a bonus talent which is nothing to sneeze at either.
As for mythic I am not as familiar with the rules having only played one mythic game (where I played a martial not a caster) and having never GMed one. However I think a good option would be to bar Advanced Talents generally and only allow them to be taken via mythic powers or mythic feats.
