Max I have is 60T (freud). Is great for cross cutting in terms of leaving a very fine cut and minimising tear out, but not so good for ripping. More effort to push through, slower and more likely to burn your work, and finer more airborne dust. I generally only use it if I am doing some cross cutting and really am afraid of potential tear out. The rest of the time I use a 24T (also freud). While the teeth are sharp even cross cutting leaves a near perfect splinter free finish.
I've never tried a 48T (I think this is what they call a combination blade?), but if I was going to go for one blade to rule them all I'd be tempted to try one.
80T seems overkill.
Nice one. Recommend you upgrade the blade to something a little nicer (eg freud) to get cleaner cuts.
If you haven't used a TS before, please watch some videos on safe use, there are a number of not so obvious things to watch out for that could really make a bad day.
Andy mac on YT has a good video should you find a spare 30 minutes. https://www.youtube.com/watch?v=eUx8oTIALmg
