There seems to be a huge number of miscellaneous projects for a specific type of environmental restoration or some other activity that is specifically aimed at carbon sequestration. For example, seagrass restoration alone has a plethora(1,2,3). Is there a decent list of these projects? I found this cool list of CCS projects(4), but that’s different.
If such a list exists, I have another question: Is there an objective way to compare their effectiveness?

There are a few reports out that group them by type.
National academy of science and engineering has one on ocean carbon: https://nap.nationalacademies.org/catalog/26278/a-research-strategy-for-ocean-based-carbon-dioxide-removal-and-sequestration
There’s also a state of carbon report from last year: https://www.stateofcdr.org/
I’d suggest Carbon Brief as a good source covering some of them: carbonbrief.org
Finally the EU had a call out last year through the Horizon Europe funding program for research groups to create a framework for carbon removal. I believe they funded 2 or 3 different projects, one of which was focused on ocean-based projects. I can’t find a link now, but they were €7mil+, 3-5 year projects, designed to comprehensively assess and compare all cdr options. They should have all launched this summer.
