There are quite a few, for free, right here in the forum. Yes, you set up the individual jobs - but, if it’s designed well - you do it all at once.
So you start with (Eg.) 100 power/100 speed and then you change one or the other by 10 - so 90 power/100 speed, then 80 power/100 speed, etc. Once you’ve got it set up you run the test on a scrap of your material and make a judgement call as to which you like best. Sometimes you follow up getting even more exact 81 power/100 speed, 82 power, 83 power, etc.
For cuts this is my favorite test:
For engraves it’s this one (since you also want to test cuts usually):
but seriously, if you do a search on here for “test” there are probably easily a dozen.
