I had responded to Larry directly. Here is my thoughts, and I still believe
they are correct.
IMO, spend the money only if:
Your house has less than 200AMP service.
or
You use electric heat.
or
You plan to USE a really BIG welder at high capacity.
The rest of the stuff listed is really minimal. It would be difficult to use
a continuous 70 AMP for everything running at once.
$800 buys quite a few tools. . .

P.S. AC, lift, compressor are all 15 amp @110V or less, unless you are talking
commercial heavy duty equipment. Buy more insulation and the AC has less work
to do.

I'm surprised no one replied to you. Here's my take after discussing
similar issues with my electrician friends.

Yes. More capacity in and around the box gives you more protection
against overloads and fires even if you never expect to use a lot of
power hungry stuff at the same time.

All power hogs. If you plan to use any simultaneously, go for the
upgrade.

A subpanel probably isn't a good solution. All the juice still has to go
though the main panel and is still subject to the limitations therein. To
my mind it provides a false sense of security. "All the new circuits are
breaker protected, what can go wrong?" This ignores what happened
upstream of the breakers. A better solution that is still cheaper than
200 amp service is a power splitter sold be someone (Square D?) that
splits the incoming lead to two breaker boxes. Now each box is doing its
protection job at its rated capacity.
