"Ik denk het wel!"

Is this one of those "it is what it is" phrases? Also, is "I really think that." correct?

So, this would be used tp make a semi-firm commitment to a proposition?

I am guessing that wel acts as an intensifier, so that it is useful to contradict a previous statement with which you disagree, or to stress your preferred option in a discussion. Seems like a handy little phrase.

Peter: John does not like golf. John: Ik houd wel van golf!

I do like golf. I do so like golf. I certainly do like it. I beg to differ: I like golf a lot.

So Ik denk het wel is open to many translations in English.

I do think so, I believe so!, I firmly believe (that), We would be well advised (to), I am convinced (the government should) etc
