"Everything Tarou does is done without giving a single thought about anyone else. He doesn't care about anyone else. That's why I say he's selfish and unbearable. "
Does this statement take into consideration all of the people that Tarou's helped in regards to FLZ and relationship issues?
"The most "feelings" we've seen him show are because he gets aroused by Ebino's boobs, gets dazzled by Ibusuki's occasional "cute panels with shoujo filters" and is in "love" with a ghost (?) who only whispers sweet things to his ear."
That's only because Tarou's been reduced to an object in the series ever since it turned into a shojo drama and switched focus on the female characters. Tarou's feelings are perfectly understandable and relatable, for the most part he just wants to avoid getting his heart broken again like what happened when Ibusuki left the country without telling him until the last minute. Outside of that, he's comfortable with the thought of spending the rest of his life with Eve, with or without a "normal" relationship - while at the same time constantly wrestling with his thoughts and emotions in regards to his relationships and his future with the three heroines, and that's mostly because everyone around him (aside from Eve) keeps trying to meddle with him. If you're going to dislike anything, dislike how the author's been writing this story ever since the initial chapters & premise and what they've done to the series' original, now-supposed main character.

"I really don't see Ibusuki/Ebino/whoever male MC ends up w/ being happy if they're treated as second fiddle so to speak, especially Ibusuki since she can see Eve (very real potential for jealousy). It would essentially be cheating imo, as Tarou would spend time w/ Eve and ignore his significant other. This doesn't seem like a happy ending to me at all"
I agree, which is why it's not something I advocate. What I advocate is Tarou being allowed to make his own decisions and be with the person who makes him happy, which is quite obviously Eve - and Eve quite obviously feels the same way (though she's been led to believe this isn't a good outcome mostly through a combination of lack of knowledge on what FLZs are capable of, and Ibusuki's manipulation). Ibusuki and Ebino should respect his wishes and his autonomy over his own life, and stop trying to tear him and Eve apart for selfish/misguided reasons.
As for how the series ends, it wouldn't surprise me at all if the author intends to do some sort of asspull like the theories you've brought up, and present it as a happy ending (or even a bittersweet one) - I've come to expect the worst when it comes to storytelling in media nowadays. At least I would've had a fun ride up until then, and I'd always have my headcanon that Tarou and Eve stayed together and lived happily ever after, whether Eve managed to acquire a real body or not.

Eve is more than Tarou's delusion at this point, as has been clearly explained and shown several times in the story at this point. Also, Tarou has had plenty of personal growth and put in plenty of effort throughout the story - I'm not sure how you can claim otherwise unless you've been ignoring everything he's done ever since Eve showed up and he progressively abandoned his 'energy-saving man' ways.
Tarou + Ibusuki is the WORST possible ending at this point, considering the entirety of Ibusuki's actions and behavior which sum up her immature selfishness. She does not deserve to get what she wants and be in a relationship with Tarou at all, and should just fuck off with her mother and leave Tarou, Eve, and Ebino alone. She's a lying, selfish, two-faced, manipulative, self-righteous self-martyr who blames everyone else around her (mostly Tarou) for her misfortunes and takes no personal responsibility. She is a cancer.
