these two certificates are not selected, they are both for you to abide by. For example, if you develop a software and then use the framework A, and then the License of A clearly states that you should include the License of A when you release your software, then when you release it, there will be two instructions: your certificate license and A's certificate license. By the same token, a software may have many certificates, but some are relatively loose. For example, MIT.

LGPL is an open source protocol of GPL designed primarily for the use of class libraries. Unlike GPL, any software that uses / modifies / derives the GPL class library must adopt the GPL protocol. LGPL allows commercial software to use the LGPL class library through class library references to (link) without the need for open source commercial software code. This allows open source code using the LGPL protocol to be referenced, published and sold by commercial software as a class library.

but if you modify the code or derivation of the LGPL protocol, all modified code, the additional code involving the modification and the derived code must use the LGPL protocol. Therefore, the open source code of LGPL protocol is very suitable to be quoted by commercial software as a third-party class library, but it is not suitable for commercial software that wants to do secondary development based on LGPL protocol code by means of modification and derivation.

GPL/LGPL protects the intellectual property rights of the original authors and prevents people from using open source code to copy and develop similar products.
