Here at the University of Louisville, we use a number of platforms. The BlackBoard LMS offers a few that are internal for faculty/Staff/Student use. However, many faculty, staff and students use some that you are probably all familiar with, such as Webex, Zoom, Go-To-Meetings because your companies might use these. Most of the ones I have attended were fine for meetings, however the presenter was not versed in good training design or delivery.
Any of these platforms can be used for effective training if designed properly, keeping the participant center to the learning. If you don't build in engagement in the form of formative evaluation (knowledge check), group work or even gaming, the participant will tend to check out. You can make your training just as engaging as you would in the classroom if it is designed properly. Here is an informative article from Zoom that gives good ideas for engagement.

The last thing I recommend is that you keep your training short with a number of sessions that might be stringed together over time to complete a topic.
I have used Zoom and Microsoft Teams (with the U of L account) and both of these work well for training, if designed and delivered properly.
