Hey justaskinaround,
It sounds like you're still having issues with your trackpad after taking those steps. We can understand wanting to know the best path to take going forward. We want to help.
To help isolate the issue further, the next step is to create a new user. Once the new user is created, please log into it, and see if the trackpad responds after the new user wakes from sleep. This article will show you how to create a new user: Set up users, guests, and groups on Mac.
If there is no change with the the new user as well, try resetting the NVRAM (nonvolatile random-access memory). This is a small part of the memory which stores some settings, including information on the display and start-up disk. Resetting it will not affect any of your personal data. Follow the steps from this article: Reset NVRAM or PRAM on your Mac.
If the trackpad is still not responding as expected when waking from sleep, ensure that you have a current backup of your MacBook data by using one of these methods: How to back up your Mac.
With the backup complete, you will then restart to the recovery partition, and reinstall the macOS. Typically when reinstalling the macOS there is no change to the data of your Mac, having a backup ensures that your data is safe. Follow these steps to reinstall the latest macOS that was installed on your Mac, from macOS recovery: How to reinstall macOS from macOS Recovery.
If you need further assistance with that, or need help setting up service, contact Apple Support here: Get Support.
Thanks!
