I am not so sure about the garlic. I have some unions (same family) planted around in my garden. The ones on a small new made bed, made from wood and compost don't do very well, while they trive in more established situations. It could be my specific situation. Somebody else maybe has experience with garlic in new beds from leaves and compost?

Same here in SW Virginia. I've grown garlic and elephant garlic for several years under several conditions:
A. with plentiful compost made partly from fresh woodchips, almost no soil.
B. aged compost with wood chips, no soil.
C. in sandy loam soil heavily amended with buried kitchen waste, mulched with composted wood chips, or plain wood chips.
D. almost un-amended sandy loam soil, mulched with fresh and with aged wood chips.
In every case, older aged wood chips made better, bigger, healthier looking garlic. Fresh chips made weaker, smaller garlic, even with plentiful diluted urine to address nitrogen deficiency.
The best results are from the soil amended with kitchen waste. This area is full of worms enjoying the rich worm food. The aged compost also has good results, also full of worms. Fresher wood chips in the soil, no worms. Wood chips as surface mulch doesn't deter the worms.
So I think my experience is that worm castings are the ideal garlic substrate, and that fresh wood chips are inhospitable to worms, reducing garlic yields. I suggest trying legumes in fresher wood chip compost, but that's more of a guess, not experience.
