There should be.

udffsck is used to check the integrity and correct errors on UDF
filesystems.

So "udftools" package should contain "udffsck" but it seems it's not
available in Debian package :-?

In theory, you can use whatever filesystem you prefer... or so it says
Wikipedia¹, but it also warns that some of them perform faster that
others, without entering into the details:
"(...) Even though it is possible to use any file system one likes, only
very few perform well on DVD-RAM. This is because some file systems
frequently overwrite data on the disc and the table of contents is
contained at the start of the disc."
