Greetings to you!

Please try the below code, I have tested in my org and it is working fine. Kindly modify the code as per your requirement.

Visualforce: 
<apex:page controller="ConRelatedWrapperC">
    <apex:form >
        <apex:pageBlock >
            <apex:pageBlockButtons >
                <apex:commandButton value="Show Selected Accounts" action="{!getSelectedAccounts}" rerender="pbTable2"/>
            </apex:pageBlockButtons>
            
            <apex:pageblockSection title="All Accounts" collapsible="false" columns="2">
                <apex:pageBlockTable value="{!accWrapList}" var="accWrap" id="pbTable1" title="All Accounts">
                    <apex:column>
                        <apex:inputCheckbox value="{!accWrap.isSelected}"/>
                    </apex:column>
                    <apex:column value="{!accWrap.acc.Name}"/>
                    <apex:column value="{!accWrap.acc.Industry}"/>
                    <apex:column value="{!accWrap.acc.Phone}"/>
                </apex:pageBlockTable>
                
                <apex:pageBlockTable value="{!selectedAccountList}" var="con" id="pbTable2" title="Related Contacts">
                    <apex:column value="{!con.Account.Name}" headerValue="Account Name"/>
                    <apex:column value="{!con.Name}" headerValue="Contact Name"/>
                    <apex:column value="{!con.Phone}" headerValue="Phone"/>
                </apex:pageBlockTable>
                
            </apex:pageblockSection>
        </apex:pageBlock>
    </apex:form>
</apex:page>

Controller: 
public class ConRelatedWrapperC {
    
    //Account List and AccountWrapper Class List Variables
    public List<AccountWrapper> accWrapList {get; set;}
    public List<Contact> selectedAccountList {get;set;}
    
    public ConRelatedWrapperC(){
        selectedAccountList = new List<Contact>();
        accWrapList = new List<AccountWrapper>();
        List<Account> accList = new List<Account>();
        accList = [SELECT Id, Name, Type, Industry, Phone, (SELECT Name, Phone, Email, Account.Name FROM Contacts) FROM Account LIMIT 10];
        for(Account a: accList) {
            //Add each Account record to AccountWrapperList
            accWrapList.add(new AccountWrapper(a));
        }
    }
    
    public void getSelectedAccounts() {
        
        selectedAccountList.clear();
        for(AccountWrapper obj : accWrapList) {
            if(obj.isSelected == true) {
                for(Contact c : obj.acc.Contacts){
                    selectedAccountList.add(c);
                }
            }
        }
    }
    
    //Account Wrapper Class.
    //This wrapper class contains both the standard salesforce object Account and a Boolean value.
    public class AccountWrapper {
        public Account acc {get; set;}
        public Boolean isSelected {get; set;}
        
        public AccountWrapper(Account a) {
            acc = a;
            isSelected = false;
        }
    }
}

I hope it helps you.
