I still haven't understood the implications of running a pruned walled vs a full blockchain wallet. What are exactly the tradeoffs? Because im sure Bitcoin is not as secure if you run it in pruned mode. From my understanding, the pruned size will be of around 1 GB of blockchain, which is great, but I want to know if it's worth it or not safety wise.

You can set the size, but the minimum is ~1 GB IIRC. The main implication I see is that if you need to rescan the blockchain for some reason you have to redownload it, verify it, drop it. If you have a full copy you can do this locally. A pruned node is not less secure because it verified all data locally, it just does not keep the data. Its also not as helpfull to the network as an unpruned node as you do not relay old blocks and thus cant help others sync up.
