Hi Frankenstein,
Pan F+ = nominally rated ISO 50
Gigabit Film = nominally ISO 40
Efke 25 = nominally 25
In medium brightness, not necessarily Bermuda or anywhere with sunny 16 conditions, these films are fine to handhold, especially with wide-angle lenses. Most are only a stop slower than ISO 100 film. Efke 25 is odd in that it's data indicates that when rated at ISO 50, it develops well. Incredible grain detail results from "very slow" film like Kodak positive release film (phenomenally detailed!! It's used as a copy neg for that reason). Its ISO is somewhere around 1 - 3. Now that is slow! The three films above are nowhere near as slow. For moving subjects, some find that chromogenic 400 ISO film is finer than traditional B&W black and white negatives. It depends on ambient lighting. Photographers in sunny countries like Greece etc don't have a problem with using Pan F+ or even the old Kodak Technical Pan off tripod.
For critical enlargement, a tripod is a good idea regardless of digital or film....camera shake shows up proportionally to the enlargement factor. A lot of photographers on the move use Pan F+ for portraiture work with a flash as well so no tripod needed.
8x10" negs - enlargement factor of 10x - wow! Now there's a billboard for you! Most of us run out of wall space before then....
