for inside i would use a silicone of some type but the filler your talking about is brittle when dried and is made to only be added to an area and sanded away to fix imperfections not really to seal gaps in things.

cut straight and use glue. you shouldnt have any spaces between the joints. if you do fill them with wood glue.

Use good wood glue and sawdust and make a paste to fill small voids/cracks. Let dry then sand then either use Silicon or fiberglass resin with hardener in it. Some times no matter how straight the wood is cut its a warp or bow in it and doesn't seal correctly.

There isn't any gaps. I just want it as strong as possible and have no 90 degree angles inside. And figured I could use the filler stuff to round all the angles inside

Woodglue clamp the pieces together for atleast 12 hours use 1.5" screws spacing every 6", let dry then do silicon in the corners.
Unless you running ungodly amounts of power and such woodglue would hold it together.. also add bracing to the inside of the box.

you should have added 45s... you dont want sharp corners in the box...
