I don't have much in the way of general advice other than "try to be inclusive toward people whose experiences and circumstances may not be like yours", in much the same way as male allies should be aware of things that can make women feel unsafe, omnivores should be aware that some folks have dietary restrictions, and so on. Money can pop up as an excluding factor pretty easily. So, for example, insist on a hard (and low, ideally ridiculously low) upper bound on any expenses associated with optional-but-not-really events like gift exchanges or potluck meals. A company-culture norm of spending higher amounts on such things can cause a lot of stress, even if the amounts are still affordable: ie. figuring out a $25 Secret Santa gift is easier than a $50, much less $75, one.
