Perhaps, you have already mentioned some but the most important thing to consider when choosing a wallet is the reputation. Because I don't just look at how much I pay but I was very concerned if my transfer went successfully or if it will just go in thin air. In many cases that this happens, may not because of the wallet or exchange destination but also because sometimes we got fake and use phishing sites. That is why we should be careful and we should not send our money too fast but rather be sure that the address and site are correct.
