Plants with different lighting requirements

I currently have a 48" Current Satellite LED Plus Pro set to around 60% for 8.5 hours a day. I also have a 48" Current Satellite LED Plus that I turn on for a few hours at night while I am home in parallel with the above Pro light.

My tank is mainly various Crypts, which if I have learned correctly are mainly low light, which is why I dial back the Pro light. Is this correct?

I have a CO2 system in the mail, as well as a giant Red Flame Sword, which sounds like a high light plant. Is this correct?

If so, how do I accommodate high light and low light in the same tank; an LED spotlight or other configuration?

I plan on 80% crypts and this one large sword.

You don't need to match the light demands for each type of plant. You need to have adequate light for the most demanding of the plants, and the lower demanding plants will grow fine with that light. Sword plants don't need high light, but like all plants, they grow faster with more light. And, more light tends to cause plants which have reddish coloration to have brighter red and more red in their color. The downside of higher light is that algae also grow much better with higher light, so, generally, having more light than your plants need can make avoiding algae much more difficult.
