Sure, why not?
Do both : high cadence days, low cadence days.
High intensity days
Low intensity days for recovery; especially after low cadence days.

High cadence will tend to work on cardiovascular while low will tend on muscle strength. Both are important but being able to spin fast is the gateway to fast acceleration. Going from 90 to 120 is a huge increase in wattage and happens really fast. You can also spin much higher for a short while before shifting up and settle on a steady cadence.
