Water coming in foundation in finished part of basement

So recently I've been having an issue with water coming in through the foundation in our finished half of the basement. This has been within the last year (2 years before without issue). It mostly only happens when we get several inches of rain in a short period of time or if there's a decent rain after a few days of rain. See video of water coming in here: https://photos.app.goo.gl/iCiR93rHhMzWRB1x5

The unfinished part of the basement has a sump pump that was able to handle most of the water around the foundation with a few weak points that would see water coming in on occasion but would go over to the drain and out of the basement.

I've read that sealing up these weak points is not recommended but I want to know if it's ok to drill into the wall here and apply some kind of concrete seal just so it's not coming in through the finished part of the basement.

I have a few theories as to why there's more water and I'm working on a few fixes that will hopefully get more water away from the house. For now I just want to deal with this one weak spot in the foundation and figure out what I can do to stop this one spot from leaking.

This needs to be the first step long before anything is done to the foundation! What is being done?

The key is always to keep water as far away from the house as possible. Then where you have a leak to the inside the best fix to to stop the water from entering in the first place. This often involves digging to install a waterproofing membrane to the outside of the foundation walls and drainage to get underground water away from the home. A distant third option is to pump the water out after it's already gotten into the house. Sort of like a bilge pump in a leaky boat. The big issue with #3 is that everything has to work. If the power or sump pump fails... you've got a wet basement.

There are a few things we're looking into.
First thing I did was have our downspouts scoped to see if there was any issue with getting the water from the roof away. No problems there except I may reroute one to connect up with a french drain I have in the back yard since it's currently draining onto the driveway.
Secondly, we have a raised bed on the side of the house that we put in last year. I fear that this is what has caused most of the problems as it get watered regularly not counting the days it rains. We'll be removing it.
