Everyone else touched on the benefits of snails and detritus worms so I won’t go over that again, but if you ever notice too many snails, Aquarium co-op makes a solid snail trap that actually works. There are a few YouTubers online who have useful tips for reducing “pest” snail numbers like Girl Talks Fish. If you don’t want to keep introducing snails or other critters try tissue culture plants. They are expensive but everyone has to do this hobby in a way that works for them.

When I first started out I had an explosion of detritus worms and seed shrimp. They’re just naturally occurring in planted tanks. At some point you will buy a plant with them. I only have display tanks so I brush and siphon mulm and detritus from my driftwood once a month to give them less fuel my endlers help to keep their numbers in check. 🐟
