Currently 1 week into a month long stay in Paris - what more should I do?

Bonjour à tout!

Firstly, this subreddit is fantastic and you're all incredibly helpful. There's so much to read here that I'd argue it's one of the best subreddits I've ever come across. Lots of helpful people and relevant information that helped me pick and choose where I'm staying and what I wished to do. Merci pour tout que vous faites!

I'm (30M) currently in Paris, originally from Ireland, I'm staying in the 10th arrondissement near Canal Saint Martin and I am staying here for a month. I'll be working here for 2 weeks starting this Monday but have had the last week off and will have the week of Friday the 19th of September off as well (I'm leaving on the 19th). I visited Paris once before when I was younger and did the usual stuff (Disneyland, go up the Eiffel Tower, visit Versailles) but this time I'm half enjoying my holiday here but also trialling living here as I may look into moving here for a few years, from Ireland.

I got here last Saturday on the 23rd of August and here's what I've done in that time:

• had some incredible food at various brasseries, bistrots and even some touristy spots

• climbed up Sacré Cœur's dome before descending the steps towards Place Des Abesses in Montmartre and further continuing my walk, ended up seeing the Moulin Rouge too accidentally

• swam in the Seine at bras de Marie

• walked from the 10th arrondissement to the Louvre, then up the Champs-Elysées to the Arc de Triomphe, then to Trocadero, then to the Eiffel Tower, then to Hotel Des Invalides, then to Notre Dame, then to Bastille before returning home all in one day

• visited Père Lachaise, was intent on visiting Parcs Des Buttes Chaumonts afterwards but then the storm kicked off and I didn't have my umbrella

• met up with one of my friends here for drinks

• shopped like a local, whether at a charcuterie/boucherie, a monoprix or a marché

• wandered throughout all of Le Marais, looking inside Le BHV Marais as well as Marché Des Enfants Rouges

• tried MANY boulangeries and cafés

• seen the sunset from Île-St-Louis

• watched many boats go through the locks on canal Saint Martin

And that's all in one week! I know to go to museums, but I'm going to try visit Musée Rodin and Musée D'Orsay next Sunday when entry is free since they're close by to each other. Would appreciate other recommendations to add to my list as I fancy a day of museum visits.

After this, I'm nearly at a loss for what I could look into next. I'm a bit nervous about being alone on this trip for the most part, so in the first few days I had so much I wanted to see and do which made it easy to forget any nerves. But now I'm nearly overwhelmed with what to keep in mind for the forthcoming weeks as this city is just so big compared to Dublin, I nearly don't know what to do with myself and would hate to miss out on anything I should do if I'm here this long. Whether that's sights to see, restaurants to visit, things to do etc.

Tl;Dr Irish guy here for a month, will be working some but will have time off. What more could you recommend I do while I'm here? Whether it's a touristy thing or something the locals do, I would prefer the latter but am open to the former.

Thank you for reading!
