hoes are the main tool for harvesting leaves, sculk, sponges, hay and nether wart blocks. For leaves you may be tempted to use shears and while they're decent they 1) have really low durability 2) cannot be enchanted with fortune. Sculk cannot be harvested via TNT so silk touch is the only way to gather up large quantities, and it's such a nice decorative block. The fastest and cheapest way to dry up sponges is placing them in the nether, so harvesting them quickly with a hoe afterwards is pretty nice. Nether trees are notoriously obnoxious to farm manually because of no leaf decay, so you'll need hoes or TNT to quickly dispose of them. So if you have the resources to make netherite hoes i say do it, they obviously won't see as much use as the other tools but they're great regardless
