A warm welcome to Mac-Forums.
As you're using a Mac from the 22nd century, we're unlikely to find anything suitable
On a serious note: depends on your budget, obviously.
I have a Thunderbolt 2 Dock from OWC.
Probably still available, but the latest version is a 14 Port OWC Thunderbolt 3 Dock - details here:

But a quick scan through Amazon or OWC (MacSales) websites bring up a lot of options.
I would just add that you get what you pay for and that you will want an independently powered Dock.
