Where to find the right affiliate network for my niche?

Looking for an affiliate network that is a good fit for my niche. I have tried several options, but the results were not always satisfactory. I understand that a lot depends on the choice of offers, but the network itself should be reliable and offer favorable conditions. Maybe someone has faced the same situation and can advise where to look for such networks? It is important that the network was known for stable payments and a good reputation. I am considering options for both physical and digital products.
