Strategy and technical audit for learning management system

We are creating a 1-2 hour course for healthcare professionals. This will be the 2nd course offered through After Cancer, Inc. I would like assistance in figuring out the best Learning Management System to use for the accredited course. The first course was created in Learn Dash and we recently transferred the hosting of it from Entrenzo to our website, www.AfterCancer.co. They are both WordPress. I have someone who was the administer of it when it was on Entrenzo working with me for anything that will be needed technically now that it's on the After Cancer website. As we create a new course for a different group of professionals I want to be open to other options, other than Learn Dash, if they would be effective and more economical in the development of this new course.

With this new course, we will be able to offer this education to all who want to take the course. Currently, we are limited to our workshops getting scheduled in-person onsite with up to 8 learners per session. That makes it impossible to be accessible and affordable to everyone. It all makes it impossible to scale our organization. Creating this online course will be pivotal in making this needed education available to all healthcare organizations, providers, and patient care teams. I don't feel I'm being too strong in stating that this will be the most important action we take in realizing our mission as an organization.
We're excited to take the step but want to be sure we're exploring options and what's possible before diving in.

We have applied for grant funding to pay development of the course as well as the marketing and operations to train the first 500 learners. If we do not receive the funding we will be considering moving forward anyway. We should know about the funding this week.
We have project coordinators standing by to work together on the individual pieces. We also have agreements in place with 12-15 clinicians to provide expert content for a piece of the course. We know the outline and objectives of the course but want to be sure we're considering the LMS system that will be the best fit for us before we proceed.
