I'm biased toward FormsViewer, of course, since that is our replacement product. It can be installed on-prem or online, and lets you continue to use your InfoPath forms. We are releasing a form designer too, which then removes any dependency on InfoPath. If you were on SharePoint Online, or planning a move to SharePoint Online, you could also consider Power Apps. Power Apps can connect to on-prem data, but I think the cost is pretty steep for licensing (at least they seem steep to me!).
