I need to replace the blade in my bench saw, it will only have very
occasional use for ripping (prob max of 1.4 cms wood), would 24 or 40
teeth be better?

a ripping blade would have less teeth, probably not be TCT and would
leave a poor finish, but it would cut fast. There is a method of
calculating how many teeth you might want but you would need to input
the motor speed, blade dia, feed rate and power and i don't know what
the formula is.

a sharp ripping blade is a joy to use but is a single purpose blade. you
know that I am sure. it isn't the same as a general purpose blade
without a lot of teeth.

10" blade?

If ripping is not the main task, then go for the combination blade
(~40T) - it will still rip, just not as fast, and everything else it
will make a nicer job of.

I just ordered a couple of new blades:

and

Very nice blades with plenty of carbide on each tooth, very pleased with
them.

The more teeth the smoother provided its not under powered or you want to
saw damp wood.
I hate power saws dangerous things.

More teeth = smoother cut. Less teeth = rougher cut, but more speed & less power to do it. The upside of more teeth is it can be good enough to do all jobs, though ripping will be slower. Any blade can manage 1.4cm.

Aldi just had some triple chip discs for 3.99 each.

I love power saws - they make some stuff so much easier to do.
Handsaws have their place, but ripping boards and panels for utility
projects isn't really one of them. If you're a "fine" woodworker, or
just like the feel of well-fettled hand tools, then knock yourself out,
but I don't think chipboard/MDF/OSB is ever going to be all that
/satisfying/ to work with, just effective when appropriately used.

As with all tools, they need to be used appropriately but that does not
make them especially dangerous if used correctly. So far every saw cut
injury I have had has been with a hand saw or one sort or another.

Yup, there are plenty of jobs where a hand tool will get it done, but I
find it hard to believe that say ripping a dozen 8' long 4x2s in half is
a task anyone is going to relish with a hand saw!
