Since it creates its own index, is there a reason why I should “carry” the entire blockchain?
It builds the index from the bitcoind blockchain, hence why you need it.
I don't think you can use systemd with WSL... you can however use it with WSL

You can't use systemd on wsl, it's not given access to base hardware functions like that. I love using WSL, it's definitely the most convenient way I've found to SSH into any other machine, VPS and, and I even use it access my VirtualBox instances.
@BlackHatCoiner, you can install Ubuntu server onto Virtual Box, start the instance in "headless" mode, and access it with WSL. The advantage is that you can copy and paste commands right from your windows desktop without installing all the VirtualBox additions. I'll be a relatively light install without any bloat, and should work for your needs.
Also note worthy; ElectrumX requires bitcoin core to run unpruned, so you will have to download the entire blockchain.
