You omit quite a bit of detail, so it's necessary to do a bit of guessing.
A bladder style pressure tank is the preferred style these days. They come with the Schrader air valve as standard. The greater capacity the tank the more water will delivered between pump cycles.
The pressure switch can be adjusted to switch on & off at a higher pressure thus providing better flow over the range of the switch limits.
Recovery time relates to the efficiency of the pump & well capacity. If a baseline reading was recorded at installation compare the current recovery time to assess the pump's effectiveness.
Changing the shower restrictor will improve pressure conservation but will not fix a degrading supply issue.
If you do replace the pump at some point record the start & stop pressures & the recovery time so you can keep an eye on its efficiency.

ClockDoc, facetman -

My new Reserve Tank is 30 gallons with a Bladder and Schrader Valve. My Pump Control is set at 22 psi ON and 45 psi OFF. I prefer to go easy on my Pump and Piping System. The Reserve Tank is set at 20 psi. It takes my Pump about 30 seconds to go from 22 psi to 45 psi in the Reserve Tank.

All facets except the Shower are very adequate. As I explained - restricting the water flow at the Shower Head gave me a nice spray that lets me shower for plenty of time (15 minutes +) without the Pump Cycling. My normal shower is 7 or 8 minutes.

It’s similar to placing your thumb over the end of a Garden Hose and extending the spray distance from 3 feet to 25 feet.

Good discussion. Thank you.
