I'm kinda curious to how high speed logic analyzers overcome some of these
problems?

Typically these do not have awfully deep buffers (in fact, in terms of
modern PC memory they're positively puny) but they do have very good
and configurable triggering setups for many common uses.

When I need a very deep storage scope (megasamples to gigasamples) I
end up using a PC and a data acquisition card (which pretty much is
your postulated project!)

The digital storage scopes that come closest to the depth and breadth
that I use are the high-end LeCroy's, but man are they expensive!
LeCroy's cheaper digital scopes also tend to match analog scope
capabilities for showing jitter noise etc. like I'm used to on analog
scopes. My feeling as a ex-nuclear physicist is that LeCroy's long
experience in nuclear instrumentation shines through in terms of how I
think of data acquisition.
