Looking for a new sensor for your project or don't know which variant of mmwave sensor would fit with your requirement.
The following table will assist you with your queries during the discovery phase.
And if you don't find an answer here then don't hesitate to put a question on the e2e forum under the sensors category.
There are so many mmwave sensor variants, can not decide which one to buy for my project?
At frequency bandwidth level mmwave sensor categorized under 60GHz and 77GHz. A further level category is Industrial (IWR) or Automotive (AWR) mmwave sensor.
60GHz device variants: IWR6443, IWR6843, AWR6843
77GHz device variants:
AWR1443, AWR1642, AWR1843, IWR1443, IWR1642, IWR1843: RF front end with R4F (MCU for user application), DSP/HWA.
AWR1243, AWR1243P, AWR2243: RF front end only devices. (no MCU for user application)
Each of the above devices has different capabilities in terms of memory, processing speed, RF power which define the max range, velocity, and resolution of object detection. Refer device comparison table in mmwave sensor datasheet documents

https://www.ti.com/lit/ds/symlink/awr2243.pdf (section 3)
Based on these parameters you can decide which device variant would fit your requirement.
Which variant of mmWave Sensor I should select?
Selection of device depends on multiple factors

How does mmwave sensor handle interference by other sensor in the scene?
Refer this white-paper on this topic- https://www.ti.com/lit/an/swra662/swra662.pdf
What are the main differences between the AWR and IWR devices?
1. AWR1xxx devices support a wider junction temperature range, -40C to 125C. IWR versions support -40C to 105C.
2. AWR1xxx devices are qualified for automotive applications as they are AECQ100 qualified and ASIL-B capable. This is not the case for IWR variants.
3. Specific to the 1642, AWR1642 has 2 CAN interfaces, one of them being CAN-FD. IWR1642 only has one CAN interface (no CAN-FD).

What are the software provided with this sensor?
TI provides SDK and DFP which provides the peripheral driver and firmware. On top of TI resource explorer provides multiple other lab applications for mmwave sensor variants.
These all software are without extra cost.
Does this sensor has integrated antenna or provide antenna design details?
To reduce the module’s form factor and cost TI has launched AoP variant of mmWave Sensor. To assist you more during development process we provide much other information in form of Antenna database, white paper, datasheet, and HW design files.

Refer this e2e thread discussing similar question
What is the main difference between resolution and accuracy in mmWave Sensors?
It is important to distinguish between "Range Resolution" and "Range Accuracy" as these are two different (but related) concepts.
Resolution refers to the minimum distance between two objects that is needed by the sensor to distinguish them apart. As of now the minimum range resolution of mmWave Sensors is just under 3 cm.
Accuracy refers to the error in actual distance compared to what is detected by the sensor. As of now mmWave sensors have seen accuracy to within .1 mm under certain conditions.
What are frequency ranges mmWave Sensors support?
mmWave Sensor has multiple variants covering two frequency band to cater region based requirement.
Can mmwave sensor be integrated with external processor or MCU?
How do I get the technical support with mmWave Sensor?
