Flower Mural Table – Some questions about the process.

Note: I just realized how long this post is, so I bolded my main questions for convenience's sake.

Hello all! I just recently bought some wooden chairs and a wooden table for a steal, and I was planning on refurbishing them for my new apartment next year. My plan is to paint the chairs a light, pastel pink, and paint the table a soft green and do a floral-mural-esque painting on the top of the table. I've been doing research for the past week on how to go about the process, and most things are clear to me (sand it first, make sure to prime and do a top coat, let it cure for the full length of time), but there are a few things I'm still unsure about and I haven't been able to find any info online to help.

For one thing: the actual paint itself. If I am certain I am going to use a semi-gloss top coat, do I need to invest in the more expensive semi-gloss paint, or can I opt for the cheaper matte/eggshell finish enamel paint? It seems kind of pointless to me to pay for a more expensive finish if I can just get the same finish with my topcoat, so am I missing something here? Is there a benefit to using the semi-gloss paint in addition to the top coat?

Secondly is the paint for the mural. I know you can't really use water-based paints on top of oil-based without primers/sealers. I think I've decided on using oil-based enamel paint for the base color of my table, so I'm not sure what will work for use on top. I was thinking about using my own student and artist-grade oil paints on the table since I already own multiple colors and this would save me money, but I'm not sure if this would cause a negative interaction with the enamel paint. Any experience here?

I was also thinking of using the leftover paint from the chairs in the mural, but I'm not sure if using the enamel paint in the same step as the oil paints would lead to a similarly negative effect. My most probable mode of attack is to do a practice run on a scrap piece of wood that I have (especially to practice the flowers), and see if anything funky happens there. With that, I'm not sure how long I should wait to see negative effects before giving myself the go-ahead on the actual thing.

Then, with the primer and top coat, I see that there are options for aerosolized versions and paint-on versions. I'm leaning towards a spray-paint primer (KILZ Original 13 oz. White Oil-Based Interior Primer Spray, Sealer, and Stain Blocker), but I'm wondering if the same benefits of spray-on primer apply to the top coat? Will there be a difference in durability or coverage?

Finally with the top coat, I am seeing mixed information online about water-based vs oil-based top coats. The issue I'm seeing with using an oil-based top coat is that they all seem prone to yellowing which, if I'm painting a mural, would not be ideal. My concern with the water-based top coats relates back to my concerns above. Can I use a water-based top coat on top of oil-based enamel paint?

The specific top coats I'm looking at include the following: General Finishes Satin High Performance Polyurethane Interior Topcoat, Rust-Oleum Protective Enamel Gloss Crystal Clear Spray Paint, Rust-Oleum Gloss Clear General Purpose Spray Paint, Varathane Clear Semi-Gloss Water-Based Interior Polyurethane. Does anyone have experience with these top coats, specifically with use over enamel paint?

Thanks in advance for any help, and if there's anything that needs clearing up, I'd be happy to provide a response.
