Hi, Daniel.
Read Gaia's Garden to the last page. There you find and precious resource: plants for a future (pfaf.org), it's an internet database with the species that you might use in your terrain, sorted by their systemic functions, edibility, and many other attributes.
Then, make a list of ecosystemic functions that are a must in a food forest: nitrogen fixer, carbon production, wildlife habitat, pollinators, perennial cover, etc. Then another list with the levels: coppice, fruit trees, undercover, shrub, herb, root, vines, funghi. Finally another list of the value you want to obtain from your system. Now, select among the species that can be grown in your terrain some that you love, that you absolutely must have. For example, I must have a plum tree, red small variety, I just love it. This plum tree is in the 2nd level, and it fulfills only the ecosystemic function of providing habitat for birds, and it produces a little bit of wood (carbon matter). So, place one mark on fruit tree level, another mark on wildlife habitat (birds), another mark on provides food (automn). Got it? Then pick another plant you absolutely love, and repeat.
As you fill the list with plants you will notice that there is some overlapping, that's fine. In fact, there should be some overlapping. Also, plants in the lower levels can have more diversity.
Once you are done with the plants you love, there comes the plants you just like, but that fills the lists that are still empty. Say you didn't pick any nitrogen fixer yet. Well, use the database, find nitrogen fixer plants for your climate, and pick one that you like. Beans? Fine, then mark all the functions of beans in your lists. Take another nitrogen fixer plant as backup, just in case, maybe elaeagnus multiflora. This is a pretty good bush for fences.
You should have filled all the items in your three lists, but just in case you didn't find anything that you like for some of the items, then pick whatever plant works there. Know that you are growing it as a support species, it's your system who needs it.
Then, try to find the species you selected. If you can't find some, then go back to the selection process and start again. Chances are that now you have a list from your local nursery with a lot of plants that aren't even in the database, but that may perform the same functions.
(Oh, I forgot, if you already have established trees, then account for them).
Then it comes the design phase, which plants go where. You draw some pathways, draw the big trees you can walk under, the shrubs. Then you mark their place on the terrain and when the season is right, you actually plant them.
If you have trouble with the design, just plant big things in rows, smaller things in adjacent rows. It's not as pretty, but it's more efficient for management.
