You can reduce lighting time more, reduce intensity of light, increase flow, add co2, reduce nutrients through water changes, add uv sterilizer or add creatures that eat algae depending on the kind and severity of algae
I had the same issue with the artificial plants and wood. I would remove all and scrub them but it would come back in a couple of weeks. After removing the wood it hasn't come back (been a few months now) im looking into a gold nugget or bristle nose pleco in the next tank

I swear by zebra nerite snails. About one per 15 gallons and your glass will be clean. They are hardy and fantastic. Alternatively, my local stores didn't have any when I lost a few so I had to try out the black cone snails. They work really well as well, but are nocturnal so you don't see them out and about as much. Both are tremendously efficient at keeping my glass clean.
Avoid plecos. They are a trash tier algae cleaner, preferring to suck on driftwood than glass. They also like to suck on slime coats and therefore aren't suitable in every tank (even those big enough to house the particular species)
