SUNLU PLA+2.0 3D Printer Filament Black+Grey 2KG and SUNLU Silk 3D Printer Filament Silk White 1KG

Well-known as much for their S1/S2 filament dryers as for the filament itself. The material catalog — PLA, PETG, ABS, TPU, silk — is broad and frequently discounted on Amazon. Solid all-around option.
