A family of Microsoft relational database management systems designed for ease of use.
Your IT department should have tools and expertise to help you export the data from an accdb or mdb to either .csv or .xlsx files. It's not difficult to do if you have the proper applications and experience.
Also any developer who has a Windows computer with Access and Excel installed on it could do this for you. You didn't specify how many tables you have exactly, but with only 2,000 records in the names table, this is a pretty small amount of data to export.
So, you'll either need to install a Windows emulator, like Parallels, on your Mac and obtain a Windows license and an M365 license to do the export yourself, or find someone to do it. If your IT department can't, you could search for Access developers who would complete the export.
The main issue, I would think, is the confidentiality or proprietary nature of the data itself. Professional developers would sign an NDA before doing it.
