But they weigh a *lot* more than anything else! I get about one or two
a year with standard Marathons, which is acceptable IMHO.

Heavier rims/tyres will change things a bit, but how much is really a
suck it and see job, I'd think.

26 is mountain bike size, 700c is the slightly larger diameter typically
seen on pure road machinery. So short answer is one won't fit on the
other. However, standard Marathons are available in loads of different
sizes (I use 16", 20" and 26" flavours myself, and I know there are 700c
ones too), so I wouldn't be surprised if there are more options on the M+.

Yes, it's the width in mm.

Rule of Thumb is that the narrower the tyre the less the rolling
resistance tends to be (given appropriate pressures), though once you're
down in the lower 20s there are other tradeoffs so there's little point
even on serious racers to ride on real knife edges.
Wider tyres will generally soak up shocks better and ride much better
over rough surfaces (roads can be rough surfaces at times!), and they're
better at taking loads.

Laden touring typically uses 38 or 35, which is a good general size area
for a "do anything" bike that'll be carting a fair load. You'll go a
bit faster on 28 or narrower still, but only a bit, and the bike won't
take on as many different conditions so well.

MTBs for Serious Mud will use tyres over 2" wide, which are Just Great
in Serious Mud and are absolute purgatory on the road because it's so
much extra work to get them rolling.

Yeah, they are the best selling ATB slick where I work. I use kevlar
lined normal marathons (28C) and they havent punctured despite being
used on towpath, road and broken glass.

I'd tend to go for the marathon because they are cheaper.
All sorts of modern tyres are a hell of a lot better in terms of punctures
than what we had as kids.
Actually if they are "snakebites" what you really need is a track pump
(cheap ones 12-20 quid).

Yep. With all due respect (and good luck to you), you could do with wide
tyres if you are 100lbs overweight.
You won't really get much of a difference in speed between the different
widths if you have decent modern tyres.
I say this as half of a "never quite been BMI>30" tandem team.
