I am tired of doing never ending research when it comes to planning a solo trip. I tried reading blogs, community articles, etc. which is good but it takes a ton of time.

Then don't? Just decide where you want to go, check out flights, lodgings, few places you definitely want to see, bookmark them in tripadvisor and just go.

I went to Japan for two weeks just before Covid with planning that took me like two evenings of googling. I booked flights, hostels in Tokyo and Kyoto, googled about interesting things to see and do in and around those cities, made a list of them in google drive, bookmarked them in tripadvisor and that was pretty much it. I did some googling later(things like how Tokyo metro and trains work, more details how to get to some locations, etc), but most of the planning was done in hours.

I had a rough plan for each day(monday: MORI digital art museum, tuesday: Imperial Palace, and so on) that I followed when I felt like it. One or two bigger locations per day, check tripadvisor and/or google maps to find something to eat, go for a drink/walk in the city/eat in a restaurant/whatever in the evening. If I didn't feel like following my plan for the day, I did something else instead.

I don't see the point of never ending research. Just decide where you want to go, arrange flights, hostels/hotels/airbnb, bookmark more stuff you want to see and do than you have time for, and go for it. When you're there, spend some time each day to finalize your plans for the next day. That's all you really need to do.
