Seeking Recommendations for Customer Journey Mapping Tools

We are beginning to draft detailed customer journey maps across numerous products, routes to market, and personas. Right now, we're using Zoom Whiteboard and it is rather... cumbersome. I'd love recommendations for journey mapping software or tools that you enjoyed working. This is going to be a long-term project, and I want to future-proof this work as best as possible (i.e. use a tool from the start that will grow with us) Separately, if you are well-versed in Zoom Whiteboard and love it, I'd love to learn from you on how to love it too 😉
