Monero wallet is likely to be very secure and reliable; its the official open source and publicly audited wallet for this multi billion dollar asset. Just make sure you have the right one .(You should compare hashes with multiple public and reputable sources as best practice)
Whether or not your funds are safe depends primarily on how you handle your private keys and seed phrase, which is a whoooole kettle of fish. The gold standard is airgapped transaction signing, for which you might would need feather wallet, which is another well loved reputable open source wallet.
