Most recently, I was looking for a new sensor cleaning kit for my Sony a7III and here are the ones which I would consider to buy (I have not tested them).
Cleaning the camera sensor is a quite straightforward process. First, you have to set your camera into cleaning mode. Then you remove the lens and remove dust from the sensor with an air blower. Next, you add cleaning liquid on the head of the swab and drag the swab from the left of the sensor to right. Then you turn the swap around and repeat the process from the right of the sensor to the left. Finally, you exit the clean mode and switch off the camera.
Altura Photo Professional Cleaning Kit
The Altura Photo Professional Cleaning Kit includes 6 Altura Photo 16mm Dry Sensor Cleaning Swabs, Altura Photo All-Natural 2oz. Cleaner, Lens Brush, Hard Carrying Case, Lens Cleaning Pen, Air Blower, 50 Sheet Lens Tissue Paper, 1 Large and Original MagicFiber Microfiber Cleaning Cloth.
The sensor cleaning swabs sweeps away invisible particles and uses the power of nature to clean without leaving streaks.
Swab Type 2 Cleaning Kit
The Swab Type 2 cleaning kit is based on non-alcoholic base water which ensures minimum friction and the static build-up micrometer level fiber sweeps invisible particles.
The cleaning-tongue is thin and flexible which ensures to spread pressure evenly over the sensor. You can find it on Amazon.

VSGO DDR24 DSLR or SLR Camera Full-Frame Sensor Cleaning Kit
This is the cleaning kit which I also use with my Sony a7 III camera. The cleaning liquid lasts actually for more swabs than the ones which come with the kid and you can buy them separately. You can find it on Amazon.
