Is it appropriate for the Academia.SE to gauge interest of the community in a potential product (service), focused on the academic market? If so, what is the best way to do that: asking a question or starting a poll (not sure, if this feature exists on this site or on SE, in general)? Note that this is not about advertising existing commercial offering, but rather about validating idea via feedback.

Stack Exchange has no poll feature and poll-like questions (e.g., “What do you think about …?”, “Would you use …?”, “What is your experience with …?”) are not welcome.
What you can do is to discuss the idea in chat or host a poll externally and advertise it on Meta, in chat or even the community ads (if it gets upvoted).
