What each method has that the other lacks

Wikipedia says crema is unique to espresso and ties it to water under very high pressure, which a plunger cannot supply. Early machines that only reached about 1.5 bar were, per the same article, "too little to produce a drink that would be considered espresso today". Pushing the plunger harder does not change that.

What to do instead

For a stronger French press, use the dense end of the NCA range, 1:10: see French press ratio. If you want real espresso, a pump machine is the route: start with the budget espresso setup checklist, and use the espresso ratio calculator once you have one. Caffeine in a shot is covered in caffeine in an espresso shot. A moka pot is another stovetop option: see the moka pot guide.
