Comparing this to https://scancode-licensedb.aboutcode.org/cc-by-sa-1.0.html which says "Copyleft Limited". Still ok?

I guess so as it aligns with "CC-BY-SA-2.0" below. Or?

It has a quite typical derivative work definition, and the licensing of derivative works must be done with the same license.
"Derivative Work" means a work based upon the Work or upon the Work and other pre-existing works, such as a translation, musical arrangement, dramatization, fictionalization, motion picture version, sound recording, art reproduction, abridgment, condensation, or any other form in which the Work may be recast, transformed, or adapted, except that a work that constitutes a Collective Work will not be considered a Derivative Work for the purpose of this License.
You may distribute, publicly display, publicly perform, or publicly digitally perform a Derivative Work only under the terms of this License,

These types of licenses we always mark with strong copyleft. Not sure why scancode uses copyleft limited. It is perhaps because this is a documentation license, and hence for documentation in principle there is less linking questions, and perhaps it could be seen more as a file level-type of license, if the content always was only documentation. But code could also be released under this license, so I don't think it is sound to derive from the type of license the content that is going to be under the license. We typically use file-level-copyleft or module-level-copyleft categories when the license itself contains a file-level/module-level limitation to the interpretation of the derivative works that should be licensed with the same license.
