Hi friend. This info for readily available AGM/EFB options is already covered in this thread so probably best to refer here: EFB versus AGM Battery
The only option missing from that thread is this one: N70 Varta Blue Dynamic EFB 12V 760CCA Start Stop & Dual Purpose - 24 Month Warranty (42 Months in non Start/Stop vehicle) - Every Battery Pty Ltd
As for Lithium options, they are stupid expensive for the battery + mount but some options here:
ECU, Fuelling & Ignition VW MK7 & 7.5 Golf – Page 2 – Euro Parts Haus
MEGALiFe MV-072 Lithium Iron Phosphate (LiFePO4) Battery – MegaLife Battery Australia
Don't forget to check on Aliexpress too.
