I will suggest you go for hardware wallets that are better than SPV wallets cause its less likely to be affected by malware and no burden of managing multiple keys.
SPV wallets are wallets that are not full clients. Meaning that you do not need to download the whole blockchain before you can use them. Neither does SPV wallet needs pruning.
Exactly, cause I think not everyone is supposed to run their full nodes unless there is some necessity for them to do. Here in case OP just wants to have better security for his assets that are stored in a wallet like Electrum and looking to increase the security further.
But running their nodes on their own servers is mandatory for anyone who seeks the utmost privacy and is not willing to rely on third part servers.
