It's important to thoroughly prune the tree, preferably in winter/early spring before bud break. If you can post a photo or two it might be helpful. But you want to maintain 4-6 main lateral branches. All the rest are fruiting wood that should be removed every 3-4 years, that is, prune off about 25-35% of the spur branches every year to keep large healthy fruit. Keep the fruiting wood separated so the apples don't get damaged by rubbing against other branches or fruit. Once you have small apples, thin them off to give the remaining fruit space. This also helps with insect control. Honeycrisp are more prone to powdery mildew.

In the commercial orchard applying tree oil solution in early spring is critical. It helps smother insect eggs and larvae of coddling moth, aphids and mites, and helps control powdery mildew. We also used sodium salt solution for chemical thinning, and sulfur spray for powdery mildew. I didn't have to deal with Japanese beetles so can't help there but refer you to control measures.

For most it isn't practical to use garden/vineyard netting on apple trees but you could do it on a single tree. It can help protect from birds and hail. It is used routinely for wine grapes. I think of tulle fabric as too fragile but yours might be better. In Japan, light penetrating fabric or paper bags are used to wrap individual apples to protect from coddling moth and all. Coddling moth is universal around the globe and chemical controls are sprayed every 2 or 3 weeks to prevent apple worm. It can also help prevent sunburn.
