Hi,
Each meeting you schedule will have a different meeting URL and different conference id. A reoccurring meeting will have the same meeting information (URL and conf ID). In Skype for Business a One Time scheduled meeting expired 14 days after the scheduled meeting time, but it looks like meetings does not expires in Teams. I tried to join meetings that was scheduled two years ago and that was no problem to join them.
With that said I think you should be able to schedule a meeting, copy the meeting URL and use some online service to make the join link shorter and easier to remember. But there is no Teams service for this.
