It won't cause any damage.
Legacy mode (a.k.a. BIOS mode, CSM boot) matters only when operating system boots. Once it boots, it doesn't matter anymore. If everything works as expected and you're happy with it, legacy mode is fine.
Advantages of UEFI boot include:
Faster boot times. UEFI can skip initialization of some devices which would be reinitialized by OS anyway- Optional extra security. You can enable Secure Boot, which checks digital signatures of OS components, ensuring that they weren't tampered with. You should combine it with BIOS password protection.
- If you're using multiple OSes, UEFI offers boot manager integrated into firmware.
- If you're using Windows, UEFI mode lets you use GPT partitioning scheme, which allows for unlimited partitions and disks over 3 TB.

great general answer - you may want to add one exception - legacy mode (sometimes?) disables TPM which can negatively impact the ability to do full disk encryption.

"UEFI offers boot manager integrated into firmware" only if said firmware properly implement the boot order part of the UEFI spec, and quite a few don't (i.e. always boot Windows'bootmgfw.efi). Laptop firmware are notable repeat offenders. Whether or not the user has access to an interactive boot menu on top of that is yet another story.
