Also watching the 2009 Star Trek movie might be an idea before seeing Picard, as although it's mostly an alternate reality, a huge part of the Picard backstory happens in a brief prime universe scene that informs the chaos in the altered past.
There's also Short Treks, which take place around Discovery and TOS mainly, but the last one of the second batch (coming early next year) is a prequel to Picard.
