The next "concorde" will be a near orbit to destination craft.
I would not hold your breath waiting for it. You will see it
in a Bond movie long before you can ride one.

For a flight from New York to Singapore, with a peak speed of 7,000 mph,
what sort of G-forces would the passengers be subjected to? I realize
that this would vary with the profile, but it sounds like the beverage
cart would be a hand full.

Depends on how you get there. Back of the envelope, 1/2 G of thrust would get
the plane up to cruise speed in about 10 minutes. Cabin gravity would be at
about 1.12 Gs total. Mind you, it'd be a pretty steep "slope". :-)

If you need solid-fuel rockets to boost you to speed, of course, acceleration is
a lot harder.

That would be no worse than a bit uncomfortable for most people. The more
interesting scenario is at the other end. Negative 0.5G horizontal would
probably require flipping the seats around so you face aft. The
alternative would be to truss up all the pax like chickens on a spit to
keep their limbs from flopping around.

No, we presume the vehicle is basically re-entering at the other end. It can do
that over a longer period, with lower accelerations. Probably would want the
pax to be wearing shoulder harnesses, though.
