Virtual Whiteboard Recommendations?

When leading meetings with virtual participants, have you found great replacements for whiteboards? I miss having the option to quickly brainstorm or map something out on the whiteboards that were usually in conference rooms. I also miss being able to collect ideas on post-its (or through other tools) for participants to review / group together / vote on / etc. together in a room. In addition to allowing us to gather and sort info, I often used the above as strategies to help our kinesthetic and/or visual learners stay engaged and process info. I've tried some of the whiteboard and similar features included with the webinar providers (Zoom whiteboard, etc), as well as a variety of online brainstorming tools in the past. But it was usually for a single project or meeting, and I'd like to start using a few tools regularly that our teams can get comfortable with. Have you found strategies or tools that are effectively replacing those types of things in an all-virtual environment? I'm eager to hear your suggestions and feedback!
