There are two Community Hue Integrations that alleviate the built-in integration's polling updates for external changes to Hue bulbs. Check those out, as they make use of a new event driven API from the Hue bridge.
Also, if you do go down the Sengled or Inovelli route, all changes to those bulbs will have to be made via the Hubitat hub. If one simply does the same with Hue bridge + bulbs, then the problem is alleviated as well. Thus, IMHO, the polling really is not too much of an issue. Just make sure Hubitat is used to always control your Hue lights and you're good to go!
