There tends to be three broad categories that i recognize right now (and itll probably change up as I grow) and they are Spirits of the Dead, Spirits of Place, and Deities
In my experience they tend to require the most tending to. They have lived a life here and have passed through the veil (or remain here). They can be some of the spirits the most invested in your path and the most capable of teaching you of your area and can be the most present or active in your space. In my experience they appreciate food and drink offerings as it gives them energy (they however dont n e e d these offerings to work in your life, but the larger the goals you want to accomplish the more energy it will require, so feeding them weekly or monthly depending on the speed you're asking for (and they agree to) is a good rule of thumb). In this thought process, learning their history, keeping a reccord of them, learning their name and what they love is also important.
This generally speaks of everything that isnt dead, and isnt a Deity. I run into mostly physical place spirits (house spirits, land spirits, tree spirits ect) but also path related place spirits (like sirens) tend to enjoy devotional acts. House spirits enjoy a keeping of a tidy (as you can manage) house, and land spirits enjoy tidying up their space (removing plastic or harmful garbage) and clearing out invasive species that are suffocating the native species of plants.
This one has the most variation. But usually in my experience they *require* the least tangible food offerings (but still enjoy it) and adore happiness (things that make you happy). So drinking your fav favorite coffee in the morning with them, in my case painting them or giving them gifts that make me think of them. Generally anything given in good faith and love is accepted (with exceptions ofc they have preferences too) as well as just listening to them and the advice they give.
