You should be able to do this exclusively using By URL Part protection. You'll need 2 plans configured as exclusive and configured to allow upgrades. Next within their Integrations > Extensions > By URL Part parameter you'll need to configure the following.
Plan 1 (view access)
option=com_comprofiler&view=pluginclass&plugin=cbgroupjive&action=allcategories
option=com_comprofiler&view=pluginclass&plugin=cbgroupjive&action=categories
option=com_comprofiler&view=pluginclass&plugin=cbgroupjive&action=allgroups
option=com_comprofiler&view=pluginclass&plugin=cbgroupjive&action=groups
With Plan 1 they should be able to view categories and groups. With Plan 2 they should be able to view categories, groups, and create/join groups.
