From here to you think I'd be better off long term to keep putting points into strength to get to the 4 point cap or start working on blocking exclusively?

It depends on how much STR you want compared to blocking.

If you want a HIGH STR build, go ahead and take it to 68 and then work on BLK. If you want more balanced, get BLK to 48 and then take STR to 68 and come back to BLK to 60 or so.
