I'd suggest you visit your local chandlery
with the best selection of line. Touch it, feel it. Record
who has made it (lots of manufacturers). Then do a compare and contrast via their websites for the strengths and recommended uses of the lines.
FWIW, we use spectra for halyards, mainsheet, and reef lines, and double braid oversized for chafe protection for genoa sheets
, and about 12 mm double braid for our staysail sheets
and double preventers. Not all line is the size it claims to be, either, weird, eh?
You will develop your own preferences through experimentation.
