Yes, there are finally F parts with LCD drivers to replace the ancient
16C923/924 in new designs.

Looks like a fairly nice 4 digit 7 segment display.

"Static" is a bad name as LCDs must not be driven with DC.  I think they are
trying to say "not multiplexed", in which case you need to have a separate
pin for each segment.

You need 33 segmennt pins, plus apparently one common.  The common pins are
handled separately.

It requires more pins but multiplexing is easier.  However, the latter
doesn't do you much good since the PIC would take care of that anyway.  A
single common can make contrast adjustment better.  So I don't think it's
harder unless you mean running more traces is harder.
