Others have written whole books about saws, tooth geometry, how to use, the various advantages of different types of saws… so instead of writing a book here I’ll tell you to go read a few.
Not even with a table saw can you get away with only having one type of blade. So you need to have a few Saws in your arsenal.
You need a good crosscut saw. these are for cutting stock to length.
You need a good rip saw, these are for cutting stock to width.
Now, a lot of our stock sizing is done with splitting and hewing. So maybe a ripsaw isn’t as critical as having a crosscut saw. But you will eventually find a place where you want to cut a slab of wood in the rip direction and cannot spare the waste of splitting and hewing. So when you get a Ripsaw make sure it is a good one.
For cutting tenons you will want a crosscut saw, you could use your big one for cutting stock down, but you will find that having a smaller one, perhaps with a back stiffener, to be very handy for this… these are called Back saws.
a coping saw is handy for small stuff and some curved cuts.
A Turning saw is good for large curved cuts.
So is a Felly saw.
and for resawing slabs to make thinner boards a big ripping frame saw or just your ripsaw can be used.
and the saw nib is just a decoration.
