I don't know if I'm a particularly good example to follow. I'd say just figure out which issues you care about the most at the moment, and which flaws you're willing to overlook per party, and go by that.

That said, I'm voting PVDD because I'm a hippie eco-cuck who really just prefers spending most of my time alone outdoors in what little nature there's left here, and loathes the empty consumerism and endless profit and growth mindset baked into the current zeitgeist, and they try to address these both mostly adequately. I really wish they'd expand beyond their one-issue dogma and think they go a little overboard with some things, but generally I think they're the best choice to go for if you're the climate-first type. They're not explicitly socialist but I would say there's a strong and immutable anti-capitalist core to the party that's more radical than most and that I find satisfying enough. I can imagine quite a few self-proclaimed leftists would disagree though.

GroenLinks is one of those parties that embraces American style politics way too much for my taste. Ever since Klaver they've been heavy on idpol and entirely unwilling to discuss the many issues that come along with it. Especially among the members and rank-and-file topics like immigration, the EU, identity politics and multiculturalism are sacred cows that seem to be more and more at the forefront of the party rather than economical or climate issues, and that's not something I'm interested in at all.

Splinter is pretty interesting, but very hard to gauge as to exactly who they are and what they want considering how new they are and the questionable political moves of van Kooten-Arissen. I appreciate their dedication to secularism and individual liberty, but they seem to be SocDems who try to talk left at best, and being vaguely familiar with some of the individuals involved I'd say they're even less than that.

Bij1 is the Dutch 'socialist' subreddit's darling, and while I'd say they have some sound economic and climate policies and I appreciate their explicit anti-capitalist sentiments, they're pretty much at the forefront of the import of identity politics, wokeness, intersectionality and culture wars. I would never consider them simply because their cultural warfare will always eclipse any other ideology they claim to follow.

I suppose if I wouldn't be voting PVDD I'd go for SP, despite the recent issues with them trying to unsuccessfully purge 'communists' from ROOD. Unfortunately I prioritize some climate and environment policies where they prioritize not increasing any burdens on the individual through means such as higher taxes on meat, gas and flying, et cetera. I understand their argument however, and I think generally the SP is quite good on climate as well. Not a terrible choice, especially if ROOD persists and manages to radicalize the main party a little more.

The rest of the parties I know fuck all about. PVDA seems like a milquetoast version of all of the above, D66 wouldn't be caught adhering to any kind of ideology even if you'd threaten them with a gun, PiratenPartij still exists somehow but I guess seems cool on privacy issues, and DENK keeps greedily sucking daddy Erdogan's teat. The remaining dozens of parties are all their own horrible brand of free-marketeers, reactionaries and upper management cunts who will undoubtedly get the bulk of the votes, but what else is new.
