Me naively thinks its better to ie put some nano foil which takes ie 5% of the light passing through on some stable orbit between earth and sun and have sun blocked without any further particulate pollution, which would end up falling on us while we breath it.
It has benefit that its position may degrade on its own over time, or be just moved when convenient. Still a gargantuan engineering project, possibly out of reach for current technology to do reliably.

A fleet of solar sails would be the cheapest and fastest, for example, it can accomplish this with great redundancy, whilst being steerable and powered using the very sun they'll block. The size of the sails would have to be huge, so a very interesting engineering problem to be solved.
