If possible, running a Bitcoin full node but it requires big storage space so if you can not afford enough disk space and other technical parameters for a Bitcoin full node operation, you can run a Bitcoin prune node.
Running a Bitcoin prune node and using it for your Bitcoin storage and transaction broadcast is still better practice than relying on nodes run by the others with SPV wallets such as Electrum wallet.

It doesn't have to be full node if a person doesn't have the fund to be spent for running a full node since it takes a lot of disk space for all the data in the blockchain. I didn't mention it but I am sure many people are aware of running a node needs a lot of disk space for full node and also aware that there's also a prune node which doesn't keep all the historical data after verification unlike the full node. For those planning to run a node but doesn't have the budget then I recommend running a bitcoin prune node.
